This is Powerpoint Presentation on IP addressing & Subnet masking. This presentation describes how IP address works, what its classes and how the subnet masking works and more.
IP addressing and subnetting allows networks to be logically organized and divided. The key objectives covered include explaining IP address classes, configuring addresses, subnetting networks, and advanced concepts like CIDR, summarization, and VLSM. Transitioning to IPv6 is also discussed as a way to address the depletion of IPv4 addresses and improve security.
This presentation gives a brief description about IP Address (Internet protocol address), Classes of IPv4. And also included, what is IPv4 and what is IPv6.
The document discusses the Internet Protocol (IP) which is the cornerstone of the TCP/IP architecture and allows all computers on the Internet to communicate. There are two main versions of IP - IPv4, the currently used version, and IPv6 which is intended to replace IPv4 and includes improvements like longer addresses. IP addresses are 32-bit for IPv4 and 128-bit for IPv6. Strategies like private addressing and Classless Inter-Domain Routing (CIDR) help conserve the limited number of available IP addresses.
The document discusses subnetting and provides an example of how to subnet the IP network address 192.168.1.128 into 6 subnets. It explains that subnetting allows a single network number to be shared among multiple physical networks. Each host is configured with an IP address and subnet mask, where the subnet is calculated by performing a bitwise AND of the IP address and subnet mask. The example shows how to determine the subnet mask is 255.255.255.224 when creating 6 subnets, and that each subnet can support up to 30 hosts.
This presentation contains why we need sub netting, how we do sub netting, CIDR, Subnet mask, Subnet mask value, Class A Sub netting, Class B Sub netting, Class C Sub netting.
This document provides an introduction to IP addressing, including:
- A brief history of IP development and the OSI and TCP/IP models.

IP addresses are 32-bit numbers that uniquely identify devices on a network. They allow for file transfers and email communication using the Internet Protocol. There are five classes of IP addresses - A, B, C, D, and E - which are divided into ranges to define large, medium, and small networks. Users can determine the IP address of their own device or other computers and websites using commands like ipconfig and ping.
An IP address is a numerical label assigned to devices in a network using the Internet Protocol for communication. It is composed of four numbers separated by periods, with each number representing eight bits for a total of 32 bits. A subnet mask defines which parts of the IP address represent the network ID and which represent the host ID. A default gateway, usually a router, delivers packets when a computer does not know the destination network.
Subnets divide a network into smaller sub-networks or subnets. Each subnet is treated as a separate network and can be further divided. When a packet enters a network with subnets, routers will route based on the subnet ID which is a combination of the network ID and subnet portion of the IP address. Subnets are only relevant for routing within an organization and are transparent outside the organization.
IP addresses are a unique identifier for devices connected to a network. They allow for the delivery of data packets across networks. The structure of IP addresses includes a network prefix that identifies the network and a host number that identifies the specific device. Techniques like subnetting, CIDR, and IPv6 were developed to address the limited available IPv4 address space and allow for more efficient allocation and routing of IP addresses.
ARP resolves IP addresses to MAC addresses for local network delivery. It uses broadcast datagrams to request MAC addresses and unicasts to reply. Proxy ARP allows routers to answer for hosts on remote networks during subnet transition. RARP and Inverse ARP work in reverse to resolve MAC addresses to IP addresses.
IP addressing provides a unique identifier for devices on a network. There are two main types - static and dynamic. IP addresses are 32-bit numbers divided into network and host portions. Classes A, B, and C determine the portions. Subnetting and CIDR allow flexible allocation. Special addresses like private and link-local are never used publicly. IPv6 uses 128-bit addressing. Tools like ping, tracert, and pathping test network connectivity. Mobile IP uses home and care-of addresses to maintain connectivity as devices move between networks, with home and foreign agents facilitating address changes. Inefficiency can occur via double crossing or triangle routing.
A MAC address is a 48-bit hardware address that uniquely identifies network interfaces for communication in an Ethernet network. It is stored in the network card's firmware and is usually written as 12 hexadecimal digits separated by hyphens. An IP address is a 32-bit logical address that identifies a device on an IP network and can be configured manually or automatically via DHCP. Private IP address ranges like 10.0.0.0/8 and 192.168.0.0/16 are non-routable and used for local area networks.
Subnet Calculation from a given IP range, using the classless Subnet mask. Calculating number of hosts in a subnet and number of subnets possible to create in a given IP range.
This document discusses subnetting and provides examples. It describes subnetting as breaking up a large network into smaller subnets. Subnetting allows creating multiple networks from a single address block and maximizes addressing efficiency. The document then provides examples of subnetting a network using CIDR notation and calculating the number of subnets, hosts per subnet, valid IP ranges, and broadcast addresses. It also discusses an example of optimally subnetting the IP addresses needed across different departments within a university based on their host requirements.
The document discusses subnet masks and how they are used to separate the network and host portions of an IP address. A subnet mask contains a binary pattern of ones and zeros that is applied using Boolean algebra to determine if an IP address is on the local network or needs to be routed externally. Default subnet masks exist for each address class, and their function is to filter out bits and identify the network address portion of a destination IP.
An IP address is a unique 32-bit number that identifies each device on a network. It allows devices to communicate by sending and receiving data packets. IP addresses are made up of a network portion and host portion, with four sections that each range from 0-255. There are five classes of IP addresses - A, B, C, D and E - that determine the number of networks and hosts. IPv4 uses 32-bit addresses written in dotted decimal notation, while IPv6 uses 128-bit addresses written in hex. IP addresses can be static or dynamically assigned by a DHCP server.

The document discusses IP addressing and subnetting. It begins by defining IP addresses and their structure as 32-bit addresses divided into four octets written in dotted decimal notation. It then covers IP address classes, identifying the class of example addresses. The document also discusses network IDs and host IDs, default subnet masks, and how to determine the appropriate subnet mask based on the number of required hosts. It provides examples of finding the network address given an IP address and subnet mask.
Ethernet is a widely used networking protocol for local area networks (LANs). It uses cables to connect multiple computers together to allow them to send data to each other. Common cable types are thick coaxial cable, thin coaxial cable, and twisted pair cables. Ethernet uses encoding schemes like Manchester encoding and differential Manchester encoding to transmit data over the cables. Ethernet has evolved over time to support higher speeds through standards like Fast Ethernet that supports 100 Mbps and Gigabit Ethernet that supports 1 Gbps, while maintaining compatibility with previous versions.
The document discusses IPv4 routing and routing protocols. It begins with an introduction to routing and how data flows between devices on the internet in the form of packets. It then covers routing components like path determination, routing tables, and routing protocols for both intra-domain (RIP, OSPF) and inter-domain (BGP) routing. It concludes with a discussion on the future of routing with IPv6 and a high-level summary of routing and routing protocols.
This document discusses Cisco Certified Network Associate (CCNA) certification and networking concepts. It includes:
- An overview of the CCNA certification and what skills it demonstrates in networking areas like LANs, WANs, routing protocols, and network access.
- Explanations of common networking devices, topologies, protocols like IP addressing and routing, and models like the OSI model.
- Descriptions of static and dynamic routing, protocols like RIP, OSPF, EIGRP, and commands used to configure routers.
IPv4 and IPv6 are different versions of the Internet Protocol. IPv4 uses 32-bit addresses which limits the available number of unique addresses, while IPv6 expanded the address space to 128 bits to accommodate many more devices. IPv6 was developed to replace IPv4 and resolve issues like its diminishing available address space as more devices connect to the internet. Some key differences are that IPv6 addresses are much longer at 128 bits compared to 32 bits for IPv4, IPv6 has a larger address space to allow for more connections, and security features like IPSec are mandatory in IPv6.
The document discusses different types of cables used for network transmission including coaxial cables, twisted pair cables, and fiber optic cables. It describes the key characteristics of common coaxial cable types like RG-58, RG-8, RG-6, and RG-59.

- The structure of IP addresses including classes, subnet masking, and CIDR
- Techniques for subnetting networks and creating more subnets and hosts including VLSM
- The transition from IPv4 to IPv6 to address the limited address space of IPv4
IPv4 addresses identify devices on the internet and consist of 32 bits represented by 4 octets separated by periods. Addresses include a network ID and host ID portion, with the division determined by the address class (A, B, C, etc). Class A uses 8 network bits and 24 host bits, Class B uses 16 network bits and 16 host bits, and Class C uses 24 network bits and 8 host bits. Subnetting and CIDR allow networks to be further subdivided to introduce subnets and supernetting.
The document discusses TCP/IP configuration and addressing. It describes:
1) The layers of the TCP/IP model including the application, transport, internet, and link layers.
2) IP addressing including public vs private addresses, IPv4 and IPv6 address formats, classes of IPv4 addresses including class A, B, C, and private addresses.
3) Networking concepts related to addressing like subnetting, supernetting, VLSM, and IPv6 addressing formats including colon hexadecimal and compressed formats.
This document outlines an agenda for a 3-day basic network training course. Day 1 covers networking fundamentals, the OSI model, IP addressing, Ethernet LANs, and starting on Cisco switches. Day 2 covers transport protocols, starting on Cisco routers, routing protocols, routing examples, and wireless LANs. Day 3 covers cable technologies, WAN technologies, basic network commands, and troubleshooting. Hands-on labs are included for switches, routers, and examples of routing configurations.
Structured models for addressing and naming make networks easier to operate and manage. Addressing and naming schemes should be assigned hierarchically from a central or distributed authority. Public IP addresses are assigned by regional internet registries, while private addresses like 10.0.0.0/8 and 172.16.0.0/12 are non-routable and used internally. The choice of static versus dynamic addressing depends on factors like network size, availability needs, and whether additional configuration is required.
IPv4 uses 32-bit addresses which limits the address space to around 4 billion addresses. It allocates addresses into classes (A, B, C) but this led to inefficient allocation. Subnetting and CIDR were developed to allow more flexible allocation of addresses and reduce routing table sizes. Subnetting divides classes into smaller subnets, while CIDR ignores classes and allows allocation on any bit boundary. This helped slow the growth of routing tables and address exhaustion.
1. The document discusses IP addressing and routing. It introduces the concepts of hierarchical addressing using IP addresses and subnets to make routing scalable in large internets.
2. Subnetting allows a single IP network number to be divided into multiple physical networks or "subnets". Each subnet is assigned a subnet number and subnet mask to identify the portion of the IP address used for the subnet.
3. Routers use subnet masks and forwarding tables containing subnet numbers, masks, and next hops to route packets between subnets and networks. This hierarchical addressing scheme reduces the routing information needed compared to using individual host addresses.

This document discusses Variable Length Subnet Masks (VLSM) and IP addressing. It begins with an overview of IP addressing fundamentals like IP address format and classes. It then explains that VLSM allows using different subnet masks for subnets of the same network, such as long masks for small subnets and short masks for large subnets. The rest of the document delves deeper into topics like hierarchical network design, subnetting, and implementing VLSM.
IP addresses are used to route packets to the correct network and device. There are two main versions: IPv4 uses 32-bit addresses divided into four groups, while IPv6 uses 128-bit hexadecimal addresses. IP addresses are classified and divided into network and host portions based on their class. Private IP ranges are used internally while public IPs are used for internet communication. Subnet masks identify the network and host portions of an IP.
the TCP/IP protocol suite involves several methods that enables communication of which IP addressing is one of those pertinent subjects that must be considered if communication must be successful.
The document provides an introduction to IP addressing and subnetting. Some key points include:
- An IP address identifies a device on an IP network and is made up of 32 binary bits divided into a network and host portion using a subnet mask.
- IP addresses are written in dotted decimal format with four octets separated by periods.
- IP addresses allow devices to communicate using TCP/IP by sending and receiving IP packets.
- IP addresses are classified into classes A, B, and C depending on the range of the first octet. Each class supports a different number of networks and hosts.
- Subnetting allows a network to be divided into multiple subnets while appearing as a single network externally using a subnet
This document discusses the Internet Protocol (IP) version 4 and 6. It describes the key tasks of IP including addressing computers and fragmenting packets. IP version 4 uses 32-bit addresses while IP version 6 uses 128-bit addresses and has improvements like larger address space and better security. The document also covers IP address classes, private addressing, subnetting, Classless Inter-Domain Routing (CIDR), and address blocks.
There are several types of IP addresses including public, private, static, and dynamic addresses. Public IP addresses are associated with an entire network while private IP addresses uniquely identify devices within a home network. Static IP addresses never change while dynamic IP addresses are temporary and change each time a device connects.
IP addresses are also classified based on version (IPv4 or IPv6), address space (A, B, C, D, E classes), and function (unicast, multicast, broadcast, anycast). Key differences between classes include the number of bits used for network vs. host identification and the total number of possible networks. Specific rules govern how network and host IDs are assigned to ensure unique identification of devices.
The document provides information about Cisco Certified Network Associate certification and networking concepts like network types, topologies, devices, IP addressing, routing, and static route configuration. It includes definitions of LAN, WAN, bus, star, ring, mesh topologies and network devices like NIC, hub, switch, router. It also summarizes the OSI model layers, IP address classes, NAT, router components, modes, static and dynamic routing. The end includes a sample static routing configuration project.
The document discusses network design using TCP/IP. It covers IP addressing, subnet masks, default gateways, and subnetting. It also discusses network security methods like IP packet filtering, encryption, authentication, and IPSec. Optimizing the subnet design, IP performance, remote subnets, and quality of service can create an effective network infrastructure.

3. Explain the different classes of IP addresses
Configure IP addresses
Subdivide an IP network
Discuss advanced routing concepts such as CIDR(Classless Inter-
Domain Routing), summarization, and VLSM(Variable Length
Subnet Masking)
Convert between decimal, binary, and hexadecimal numbering
systems
Explain the differences between IPv4 and IPv6
4. An IP address has 32 bits divided into four octets
To make the address easier to read, people use decimal numbers
to represent the binary digits
– Example: 192.168.1.1
Dotted decimal notation – When binary IP addresses are written
in decimal format
5. MAC address –
Identifies a specific NIC in a computer on a network –
Each MAC address is unique – TCP/IP networks can use MAC
addresses in communication
Network devices cannot efficiently route traffic using MAC addresses
because they: –
Are not grouped logically
Cannot be modified
Do not give information about physical or logical network
configuration
IP addressing –
Devised for use on large networks
IP addresses have a hierarchical structure and do provide logical
groupings
IP address identifies both a network and a host
6. Class A –
Reserved for governments and large corporations throughout the
world
Each Class A address supports 16,777,214 hosts
Class B –
Addresses are assigned to large- and medium-sized companies
Each Class B address supports 65,534 hosts
7. Class C –
Addresses are assigned to groups that do not meet the qualifications
to obtain Class A or B addresses
Each Class C address supports 254 hosts
Class D –
Addresses (also known as multicast addresses) are reserved for
multicasting
Multicasting is the sending of a stream of data (usually audio and
video) to multiple computers simultaneously
8. Class E –
Addresses are reserved for research, testing, and experimentation
The Class E range starts where Class D leaves off
Private IP ranges –
Many companies use private IP addresses for their internal networks
Will not be routable on the Internet
Gateway devices have network interface connections to the internal
network and the Internet
Route packets between them
9. IP addresses identify both the network and the host –
The division between the two is not specific to a certain number of octets
Subnet mask –
Indicates how much of the IP address represents the network or subnet
Standard (default) subnet masks: –
Class A subnet mask is 255.0.0.0
Class B subnet mask is 255.255.0.0
Class C subnet mask is 255.255.255.0
TCP/IP hosts use the combination of the IP address and the subnet mask
To determine if other addresses are local or remote
The binary AND operation is used to perform the calculation
Subnetting –
Manipulation of the subnet mask to get more network numbers
Subnet address –
Network is identified by the first, or first few, octets
A TCP/IP host must have a nonzero host identifier
Broadcast address –
When the entire host portion of an IP address is all binary ones
Examples: 190.55.255.255 and 199.192.65.63
10.
11. Flooded broadcasts –
Broadcasts for any subnet
Use use the IP address 255.255.255.255
A router does not propagate flooded broadcasts because they
are considered local
Directed broadcasts are for a specific subnet –
Routers can forward directed broadcasts
For example, a packet sent to the Class B address
129.30.255.255 would be a broadcast for network 129.30.0.0
12. Reasons for subnetting –
To match the physical layout of the organization
To match the administrative structure of the organization
To plan for future growth
To reduce network traffic
13. When network administrators create subnets –
They borrow bits from the original host field to make a set of
sub networks
The number of borrowed bits determines how many sub
networks and hosts will be available
Class C addresses also can be subdivided –
Not as many options or available masks exist because only
the last octet can be manipulated with this class
14.
15.
16. Suppose you had a network with: –
Five different segments
Somewhere between 15 and 20 TCP/IP hosts on each network segment
You just received your Class C address from ARIN (199.1.10.0)
Only one subnet mask can handle your network configuration:
255.255.255.224
This subnet mask will allow you to create eight sub networks and to
place up to 30 hosts per network
Determine the subnet identifiers (IP addresses)
Write the last masking octet as a binary number
Determine the binary place of the last masking digit
Calculate the subnets
Begin with the major network number (subnet zero) and increment by
32
Stop counting when you reach the value of the mask
Determine the valid ranges for your hosts on each subnet
Take the ranges between each subnet identifier
Remove the broadcast address for each subnet

21. Classless Inter-Domain Routing (CIDR) –
Developed to slow the exhaustion of IP addresses
Based on assigning IP addresses on criteria other than octet
boundaries
CIDR addressing method allows the use of a prefix to designate the
number of network bits in the mask –
Example: 200.16.1.48 /25 (CIDR notation)
The first 25 bits in the mask are network bits (1s)
The prefix can be longer than the default subnet mask (subnetting) or it
can be shorter than the default mask (supernetting)
22. Summarization –
Also know as route aggregation or supernetting
Allows many IP subnets to be advertised as one
Reduces the number of entries in the router’s routing table
Summarize a group of subnets
Count the number of bits that are common to all of the networks
you want to advertise
Then use the prefix that identifies the number of common bits
23. Variable length subnet masking (VLSM) –
Allows different masks on the subnets
Essentially done by subnetting the subnets
Basic routing protocols such as RIP version 1 and IGRP
Do not support VLSM because they do not carry subnet mask
information in their routing table updates
Are classful routing protocols
RIP version 2, OSPF, or EIGRP are classless protocols
24.
25.
26. IP version 4 (IPv4) – The version of IP currently deployed on most systems
today
IP version 6 (IPv6) – Originally designed to address the eventual depletion
of IPv4 addresses
CIDR has slowed the exhaustion of IPv4 address space and made the move
to IPv6 less urgent – However, CIDR is destined to become obsolete
because it is based on IPv4
Network address translation (NAT) – Another technique developed in part
to slow the depletion of IPv4 addresses – Allows a single IP address to
provide connectivity for many hosts
NAT is CPU intensive and expensive – Some protocols do not work well
with NAT, such as the IP Security Protocol (IPSec)
IPv4 does not provide security in itself – Has led to security issues with
DNS and ARP
Security concerns were factored into the design of IPv6
IPv4 networks rely on broadcasting – Inefficient because many hosts
unnecessarily see and partially process traffic not ultimately destined for
them
IPv6 does away completely with broadcasting and replaces it with
multicasting
IPv6 addresses are 128 bits compared with IPv4’s 32-bit structure
27. IPv6 addresses are expressed as hexadecimal numbers – Example:
3FFE:0501:0008:0000:0260:97FF:FE40:EFAB
IPv6 can be subnetted – CIDR notation is also used with IPv6
Example: 2001:702:21:: /48
Organizations requesting an IPv6 address may be assigned a /64 prefix
– Minimum subnet with space for over a billion hosts
28. Dual stack –
Involves enabling IPv6 on all routers, switches, and end nodes but
not disabling IPv4
Both version 4 and version 6 stacks run at the same time
Tunneling –
Encapsulates IPv6 traffic inside IPv4 packets
Done when portions of a network are running IPv6 and other
network areas have not been upgraded yet
Greatest concern: security
29. The ICANN and the ARIN work together to subdivide and issue
addresses for Internet clients
Three classes of addresses (A, B, and C) are available to organizations
The two additional address categories are Class D and Class E
Subnetting involves subdividing assigned addresses
Routing tables can be created manually and dynamically
Advanced routing protocols such as RIP version 2, OSPF, and EIGRP
support variable length subnet masking (VLSM)
The hexadecimal numbering system is also known as base 16 because
it has 16 available numerals
IPv6 is the latest version of IP addressing
