DHCP evolved from RARP and BOOTP protocols to dynamically assign IP addresses to clients on a network. The DHCP server maintains a pool of IP addresses and configuration information. When a client requests an IP, the DHCP server allocates one from the pool along with other configuration and leases it to the client for a set time. This allows for IP addresses to be reused more efficiently as clients connect and disconnect from the network.
DHCP (Dynamic Host Configuration Protocol) is a standard protocol that allows devices on a network to obtain IP addresses and other network configuration parameters automatically from a DHCP server. The DHCP client-server model involves clients broadcasting requests and servers responding with offers of IP addresses and network information. Servers track IP address leases in databases to allow for dynamic allocation and recycling of addresses over time as clients join and leave the network. DHCP supports both static and dynamic allocation of IP addresses to provide flexibility in network configuration.

The document discusses the Dynamic Host Configuration Protocol (DHCP). DHCP allows network devices to request and obtain IP addresses and other configuration information automatically from a DHCP server. When a device boots up or connects to the network, it will broadcast a DHCP discover message. A DHCP relay forwards the request to the DHCP server, which will provide an IP address and other configuration parameters to the client through a DHCP offer message. Addresses are leased for a period of time before needing renewal to allow for dynamic allocation and reuse of addresses. This automatic provisioning simplifies network configuration management.
DHCP automatically assigns IP addresses to computers on a network. It uses a four-step process (DHCP discover, offer, request, and acknowledge) to lease IP addresses with default durations of 8 days. DHCP servers maintain address pools and can grant static reservations. Relay agents are required for DHCP to function across routers by forwarding broadcast packets as unicast.
DHCP dynamically assigns IP addresses and other network configuration parameters to clients. It simplifies network installation and maintenance.

DHCP is a protocol that dynamically assigns IP addresses and other network configuration parameters to devices on a network. It uses a client-server model where DHCP clients make requests to DHCP servers which maintain pools of addresses. A DHCP client will broadcast requests at initialization and use a 4-step process to get an address assigned. It will later enter renewal states to extend its lease before initialization again if needed. This allows for efficient dynamic allocation and management of IP addresses on a network.

The document discusses DHCP (Dynamic Host Configuration Protocol). DHCP is a network protocol that dynamically assigns IP addresses to devices on a network. When a device connects to a network, it sends a DHCP request to obtain an IP address and other network configuration information from a DHCP server. This allows devices to connect to the network and communicate without needing manual configuration of IP addresses.
This document discusses the Dynamic Host Configuration Protocol (DHCP). DHCP allows devices on a network to obtain IP addresses and other network configuration information automatically from a DHCP server. It is a client-server protocol that involves 4 steps: discovery of the DHCP server, offers of IP addresses from one or more servers, a request from the client for a specific offered address, and an acknowledgment from the server with the assigned address. DHCP simplifies network administration by automating the assignment of IP addresses and configuration settings to devices on the network.
DHCP allows devices on a network to obtain IP addresses and other configuration information automatically from a DHCP server. The document discusses DHCP's history from BOOTP, its purpose in dynamically assigning IP addresses, and the message formats and state machine involved in the allocation process. Key aspects include DHCP clients broadcasting discovery messages to locate servers, servers responding with address offers, and an acknowledgment exchanged upon address selection.
The document discusses DHCP (Dynamic Host Configuration Protocol), which automatically assigns IP addresses and other network configuration settings to devices on a network. It works using a client-server model, with DHCP clients broadcasting discovery messages and DHCP servers responding with offered addresses. The DHCP process involves clients sending discovery messages, servers responding with offered addresses, clients requesting an address, and servers acknowledging the address assignment. IP addresses are assigned through leases that periodically renew to keep devices configured on the network.
DHCP stands for dynamic host configuration protocol. What it does is dynamically assign network settings from a server. In other words, instead of having to configure the parameters related to how your computer communicates with a network, it happens automatically.
Assigning an IP address dynamically is the most basic piece but there is a lot more to DHCP. This includes the netmask, host name, domain name, gateway and name servers. In addition, DHCP can supply other information such as a time server.
Many people are anti-DHCP, because they see it as a way that an ISP offers you an IP address that changes. This, of course, makes it difficult to advertise a server. On the other hand, DHCP can save you a lot of ongoing configuration work within your company or organization.
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to computers on a network. It uses a four-step process (DHCP Discover, Offer, Request, Acknowledge) to lease IP addresses with default durations of 8 days, with clients attempting to renew leases at 50% of the lease time. DHCP servers are configured by creating scopes to distribute address pools and reservations for specific clients. Relay agents are used to allow a single DHCP server to service multiple subnets by forwarding DHCP packets across routers.
This ppt contains what is dhcp, it's need, advantages, disadvantages, IP address assignment process and types, DHCP architecture and lastly some differences.
The document discusses Dynamic Host Configuration Protocol (DHCP). DHCP is a function that automatically assigns temporary IP addresses to devices connecting to a network. It eliminates the need for manual, static address assignment. DHCP resides on a router or server and assigns IP addresses from a predefined range. The process involves DHCP discovery, offering an IP address, a client request, and server acknowledgement of the assigned address with a lease duration.
DHCP is a protocol that automatically assigns IP addresses and other network configuration parameters to clients. It allows administrators to change network settings centrally on the DHCP server rather than having to configure each client individually. The DHCP server uses the dhcpd.conf configuration file and dhcpd.leases database to manage IP addresses and other settings for clients on the network. The DHCP relay agent can forward requests from clients without a local DHCP server to servers on other subnets.
DHCP is a protocol that automatically assigns IP addresses and other network configuration settings to clients. It allows administrators to change network settings centrally on the DHCP server rather than having to configure each client individually. The DHCP server stores lease information in /var/lib/dhcp/dhcpd.leases and is configured using /etc/dhcpd.conf which defines IP pools, default routes, DNS servers and other options. The DHCP relay agent forwards requests from clients without a local DHCP server to servers on other subnets.
The DHCP process allows devices to request and obtain IP addresses from a DHCP server. The server assigns IP addresses, subnet masks, default gateways and DNS servers to clients. Assigned addresses expire after a lease period and clients must renegotiate with the server. DHCP operations involve clients broadcasting requests, servers responding with offers, clients selecting an offer and acknowledging the assignment.
The document provides instructions on configuring DHCPv4 services. It discusses DHCPv4 concepts like how DHCPv4 operates between clients and servers using messages like DHCPDISCOVER, DHCPOFFER, DHCPREQUEST and DHCPACK. It then provides steps to configure a DHCPv4 server by excluding addresses, defining pools, and assigning default gateways and DNS servers. Additional sections explain how to configure a DHCPv4 relay on a router to forward requests to a server, and how to configure a Cisco router as a DHCPv4 client.
The document provides information about configuring DHCP in Cisco IOS including:
- DHCP provides configuration parameters like IP addresses and lease times to network hosts from a DHCP server.
- By default, Cisco routers include DHCP server and relay agent software. DHCP supports automatic, dynamic, and manual IP address allocation.
- Configuring DHCP involves enabling DHCP services, configuring excluded addresses, DHCP pools for available addresses, and optional settings like DNS servers and lease times. Manual bindings can also be configured to assign specific addresses.
The document discusses configuring a DHCP server on Linux. It begins by explaining what DHCP is and its components. It then discusses installing the ISC DHCP server package and updating the system. The document outlines configuring the DHCP server through editing the configuration file to define options like the address pool and default gateway. It also discusses binding the server to an interface and starting the server. Finally, it shows testing the DHCP server by having another device request an IP address and checking the DHCP lease list to confirm the server assigned an address from the pool.
The Dynamic Host Configuration Protocol (DHCP)
provides a framework for passing configuration information
to hosts on a UDP network. Computers that are connected to
IP networks must be configured before they can communicate
with other hosts. The most essential information needed is
an IP address. DHCP eliminates the manual task by a network
administrator. DHCP is based on the Bootstrap Protocol
(BOOTP), adding the capability of automatic allocation of
reusable network addresses and additional configuration
options. DHCP captures the behavior of BOOTP relay agents,
and DHCP participants can interoperate with BOOTP
participants. Proposed system, i.e., Customized DHCP aims
to give the security for DHCP, which was not present in the
older one and it uses UDP instead of TCP thus reducing the
number of fields as compared to the old DHCP, in turn which
decreases the execution time and still providing the basic
functionality of the usual DHCP.
Bootstrap Protocol (BOOTP) is a networking protocol that automatically provides devices with IP addresses and other network configuration when connecting to a network. It uses DHCP and UDP to make address requests and handle responses. When a BOOTP client boots up, it broadcasts its MAC address as a request. The BOOTP server responds with an IP address, hostname, subnet mask, and other configuration details.
DHCP is an updated version of BOOTP that dynamically assigns IP addresses and other network configuration to devices on a network. A DHCP server manages a pool of IP addresses and provides them to clients through a four step request/offer process. DHCP offers benefits over static addressing like reduced errors and centralized management of addresses.

Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

Dynamic Host Configuration Protocol (DHCP) is a network management
protocol used to dynamically assign an IP address to device, or node, on a
network so they can communicate using IP (Internet Protocol).
DHCP automates and centrally manages these configurations.
There is no need to manually assign IP addresses to new devices. Therefore,
there is no requirement for any user configuration to connect to a DHCP based
network.
DHCP can be implemented on local networks as well as large enterprise
networks.
DHCP is the default protocol used by the most routers and networking
equipment.
DHCP is also called RFC (Request for comments) 2131.
3. DHCP manages the provision of all the nodes or devices added or
dropped from the network.
DHCP maintains the unique IP address of the host using a DHCP
server.
It sends a request to the DHCP server whenever a
client/node/device, which is configured to work with DHCP,
connects to a network. The server acknowledges by providing an
IP address to the client/node/device.
DHCP is also used to configure the proper subnet mask, default
gateway and DNS server information on the node or device.
There are many versions of DCHP are available for use in IPV4
(Internet Protocol Version 4) and IPV6 (Internet Protocol Version
6).
4. DHCP port number for server is 67 and for the
client is 68.
It is a Client server protocol which uses UDP
services.
IP address is assigned from a pool of addresses.
In DHCP, the client and the server exchange
mainly 4 DHCP messages (discovery, offer,
request, and ACK) in order to make a connection,
also called DORA process
5. DHCP is based on a client-server model and based on discovery, offer,
request, and ACK.
The complete DHCP exchange involves the above four types of packets:
Discover, for your computer to locate the DHCP server; Offer, for the
server to offer an IP address; Request, for your computer to ask for an
offered address; and Ack, for the server to grant the address lease.
6. The operation is initiated with a broadcasting request
by the client depending upon the client and server’s
location, which could be any one of the following
Same network - Client and server are present on the
same network
Different network - Client and server are present on
different network
7.
8. A open command is provided by the server on UDP port number
67.
Server waits for the client to respond
The server gets the response from the booted client on port
number 68
A connection is now established between the source port 67 and
destination port 68 by the server acknowledging with either a
broadcast or unicast message.
9.
10. As the client is unaware of the server, a DHCP request is
broadcasted.
A relay agent (host) is used, as the router discards the broadcasted
IP datagram.
This relay agent is aware of the server’s address and hence listens
on UDP port 67 for the messages
The received message is enfold in a unicast datagram (with the
destination address) and sent to the server by the relay.
It reaches the server through any router
11. DHCP server: A networked device running the DCHP service
that holds IP addresses and related configuration information.
DHCP client: The endpoint that receives configuration
information from a DHCP server. This can be a computer,
mobile device, IoT endpoint or anything else that requires
connectivity to the network. Most are configured to receive
DHCP information by default.
IP address pool: The range of addresses that are available to
DHCP clients. Addresses are typically handed out sequentially
from lowest to highest.
12. Subnet: IP networks can be partitioned into segments known
as subnets. Subnets help keep networks manageable.
Lease: The length of time for which a DHCP client holds the
IP address information. When a lease expires, the client must
renew it.
DHCP relay: A router or host that listens for client messages
being broadcast on that network and then forwards them to a
configured server. The server then sends responses back to the
relay agent that passes them along to the client. This can be
used to centralize DHCP servers instead of having a server on
each subnet.
13. All Dynamic Host Configuration Protocol
(DHCP) messages include a FIXED format
section and a VARIABLE format section.
The fixed format section consists of several fields
that are the same in every Dynamic Host
Configuration Protocol (DHCP) message.
The variable format section in the Dynamic Host
Configuration Protocol (DHCP) contains
"OPTIONS", which carry additional configuration
parameters.

16. Reliable IP address configuration. DHCP minimizes configuration errors caused by
manual IP address configuration, such as typographical errors, or address conflicts
caused by the assignment of an IP address to more than one computer at the same time.
Reduced network administration. DHCP includes the following features to reduce
network administration:
◦ Centralized and automated TCP/IP configuration.
◦ The ability to define TCP/IP configurations from a central location.
◦ The ability to assign a full range of additional TCP/IP configuration values by means
of DHCP options.
◦ The efficient handling of IP address changes for clients that must be updated
frequently, such as those for portable devices that move to different locations on a
wireless network.
◦ The forwarding of initial DHCP messages by using a DHCP relay agent, which
eliminates the need for a DHCP server on every subnet.
17. DHCP is used to assign IP addresses to hosts
or workstations on the network
Two types of IP addresses:
Static
Is a number that is assigned to a computer by an Internet
service provider (ISP) to be its permanent address on the
Internet
Dynamic
The temporary IP address is called a dynamic IP address
18. Important when it comes to adding a machine
to a network
When computer requests an address, the
administrator would have to manually
configure the machine
Mistakes are easily made
Causes difficulty for both administrator as well as
neighbors on the network
DHCP solves all the hassle of manually adding
a machine to a network
19. When DHCP server is unavailable, client is
unable to access enterprises network
Your machine name does not change when
you get a new IP address
20. DHCP is an unauthenticated protocol
When connecting to a network, the user is not
required to provide credentials in order to obtain
a lease
Malicious users with physical access to the
DHCP-enabled network can instigate a denial-of-
service attack on DHCP servers by requesting
many leases from the server, thereby depleting
the number of leases that are available to other
DHCP clients
