guest60ba5d

Subnetting is the process of taking one IP network address and dividing it into two or more sub-networks to create smaller network segments. It is done to add more local area networks, free up bandwidth, and localize departments. An IP address is made up of 32 bits divided into four octets, and subnetting works by splitting the address into a network and host portion to establish multiple sub-networks.

Report on ip addresses

Amandeep Kaur

IP is the protocol that handles addressing and routing of data across the internet. Each device connected to the internet has a unique IP address that is used to identify it and route data to it. There are different classes of IP addresses that determine the number of devices that can be connected to a network. IP addresses are represented numerically in dot-decimal notation and newer versions of IP have expanded the available address space to meet growing internet demands.

This document provides an overview of IP subnetting, troubleshooting, and network address translation (NAT). It begins by explaining the benefits of subnetting networks, such as reduced traffic and optimized performance. It then discusses how to create subnets by taking bits from the host portion of IP addresses. Several examples are provided of how to subnet Class C networks using different subnet masks. The document also covers troubleshooting IP addressing issues and using command line tools like ping. Finally, it describes network address translation, including different types like static and dynamic NAT, and how NAT works to allow private IP addresses to access the public internet.

Module 6 ip addresing

Charlette Tolentino

This document discusses IP addressing and subnetting. It begins by explaining IP addresses, which are 32-bit identifiers for devices connected to the Internet. IP addresses are divided into classes based on the values of their most significant bits, with Class A having 8 network bits, Class B having 16 network bits, and Class C having 24 network bits. The document then covers subnetting, which adds additional network bits to IP addresses, creating hierarchical subnetworks and conserving address space. It also briefly discusses supernetting, which combines network blocks into larger supernetworks.

CCNA 1 Routing and Switching v5.0 Chapter 8

Nil Menon

This document chapter discusses IP addressing and provides objectives for learning about IPv4 and IPv6 addressing structures, types of addresses, and network connectivity testing tools. Specifically, it will cover the binary and decimal structures of IPv4 addresses, subnet masks and how they define the network and host portions of an IP, the different types of IPv4 unicast, broadcast and multicast addressing, public vs private IP address spaces, the motivation and features of IPv6, and how to configure and test basic IPv4 and IPv6 connectivity.

Ip addressing

techittricks

TCP/IP is the protocol that governs internet addressing and routing. The IANA and IETF define IP address types and classes, including Class A addresses from 0-127, Class B from 128-191, and Class C from 192-223. Routing protocols like RIP, IGRP, EIGRP, OSPF, and BGP search for the shortest path between routed protocols like IP, IPX, and Appletalk that carry data packets. IP version 4 uses 32-bit addresses while IP version 6 uses 128-bit hexadecimal addresses.

what is Private and publis ip address

Amit Kumar , Jaipur Engineers

Private IP addresses are commonly used for home, office, and enterprise local area networks when globally routable addresses are not mandatory or available. Private IP addresses were originally defined under IPv4 to delay address exhaustion, and are also a feature of IPv6. The most common uses of private IP addresses are for residential networks, where ISPs allocate a single public address but homes have multiple devices, and for corporate networks not directly connected to the internet for security reasons.

Internet Protocol

Jayesh Chauhan

IP specifies the format of packets and an addressing scheme to allow communication between devices on a network. While IP alone only supports one-way transmission like a postal system, TCP/IP establishes two-way connections between hosts to allow them to send messages back and forth. IP addresses are unique identifiers for network interfaces, consisting of a network prefix and host number. IP addresses are divided into classes A-E based on their format and usage. Subnetting allows networks to be divided into smaller subnetworks to better utilize blocks of addresses.

CCNA 1 Routing and Switching v5.0 Chapter 9

Nil Menon

This chapter discusses subnetting and IP addressing. It covers subnetting IPv4 and IPv6 networks to segment large networks into smaller subnetworks for improved routing and performance. Variable length subnet masking (VLSM) allows more efficient use of addresses by allocating different subnet mask lengths. The chapter also addresses planning and designing addressing schemes, including considerations for network requirements and structured allocation of addresses.

I pv4 subneting

tivang yem

This document provides an overview of IPv4 subnetting. It defines IP and IP addresses, and distinguishes between public and private IP addresses. It explains subnet masks versus prefix lengths and how to assign IP addresses. The key parts of an IP address are identified as the network ID and host ID. Specific IP address classes and private IP address ranges are listed. The roles of network IP, host IP, and broadcast IP are defined. Methods for converting IPv4 addresses and subnet masks to binary are introduced, as are CIDR and VLSM concepts.

Mod6

Alam Garcia

The document discusses IP addressing concepts including: 1. IP addresses are represented in binary and decimal, and methods to convert between the two. IPv4 addresses are 32-bit numbers that are commonly shown in dotted decimal notation. 2. IP networks are divided into a network portion and host portion using subnet masks. Common subnet masks like /24, /16, and /8 define the traditional IP address classes. More flexible classless addressing allows any prefix length. 3. Key addressing concepts include private vs public IP addresses, network vs broadcast addresses, subnetting to create more networks from an existing range, and utilities like ping and traceroute.

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.

Subnets

Naresh Gotad

This document discusses subnetting and classless inter-domain routing (CIDR) in TCP/IP networks. It defines subnetting as dividing a network into subnets using parts of the host ID. CIDR is introduced to avoid depletion of class B addresses by subnetting them and assigning as class C addresses. It also folds network IDs to simplify routing table entries. Supernetting is discussed as using a subnet mask to represent multiple classful network IDs with a single entry in internet router tables.

CCNA v6.0 ITN - Chapter 07

Irsandi Hasan

The document provides instructor materials for a chapter on IP addressing in CCNA Routing and Switching. It covers IPv4 and IPv6 network addresses, including binary and decimal conversion, address structures, types of IPv4 addresses such as unicast, broadcast and multicast, and public vs private IP addresses. It also describes how to verify network connectivity using ICMP ping and traceroute utilities.

Ip v4 & ip v6

Ronan Dunne, CEH, SSCP

IPv4 is the current version of the Internet Protocol but has limitations including a limited 32-bit address space that is nearly depleted, lacking built-in network security, and limited quality of service capabilities. IPv6 was developed to address these issues by using a larger 128-bit address space to avoid scarcity, incorporating IPsec to provide security, and improving quality of service and auto-configuration features. While IPv6 adoption is still growing, transitioning networks to be dual-stacked with both IPv4 and IPv6 ensures compatibility and avoids missing traffic from users on IPv6-only networks.
