There are two ways to configure Ip address . One method is to do this manually .And other is to do this using dynamic host configuration protocol.
Automatic Private Internet Protocol Addressing (APIPA) is a common alternative to the use of the Dynamic Host Configuration Protocol (DHCP) to request and retrieve an Internet Protocol (IP) address for a host. APIPA simplifies the assignment of IP address and subnet-mask configuration information to hosts in small networks. When APIPA is used, the operating system allows the assignment of a unique IP address to each station on a small local area network (LAN). This avoids the administrative overhead of running a DHCP server or manually setting IP configuration information.
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the sub net mask and default gateway. For any further detail, so you can visit this website:http://www.iyogibusiness.com Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain necessary TCP/IP configuration information from a DHCP server. If you want to more further detail so you can visit this website:http://www.iyogibusiness.com DHCP (Dynamic Host Configuration Protocol) is a network protocol that enables a server to automatically assign an IP address to a computer.
At the network layer, the protocol commonly used to obtain an IP address is the Dynamic Host Configuration Protocol (DHCP). DHCP allows devices to request and receive an IP address and other network configuration parameters automatically from a DHCP server. This process involves a series of messages exchanged between the client and server, including DHCP Discover, Offer, Request, and Acknowledgment. By using DHCP, devices can join a network with minimal manual configuration.
If a device does not receive an IP address from a DHCP server, it may resort to using a link-local IP address, often in the range of 169.254.0.1 to 169.254.255.254. This automatic configuration allows the device to communicate with other devices on the same local network segment without needing a DHCP server. This process is part of the Automatic Private IP Addressing (APIPA) protocol.
IP address
The protocol that automatically configures IP settings for a client is called Dynamic Host Configuration Protocol (DHCP). DHCP allows devices on a network to receive IP addresses and other network configuration parameters automatically, eliminating the need for manual configuration. When a client connects to the network, it sends a request to the DHCP server, which then assigns an available IP address and provides additional information like the subnet mask, default gateway, and DNS servers.
Ifconfig
Reverse Address Resolution Protocol, obsoleted by BootP and DHCP, allows a computer to obtain an IP address after it has obtained an ethernet address. Bootstrap Protocol allows a computer to obtain an IP address when the operating system is starting up.
BOOTP stands for Bootstrap Protocol, a network protocol used to automatically assign IP addresses and configure network settings for devices on a network. It was primarily designed for diskless workstations to obtain an IP address and bootstrap information from a server. BOOTP allows clients to request an IP address and other configuration details from a server, which responds with the necessary information. While largely replaced by DHCP (Dynamic Host Configuration Protocol), BOOTP is still relevant in some legacy systems.
The port that automates the assignment of IP addresses on a network is typically associated with the Dynamic Host Configuration Protocol (DHCP). DHCP servers use UDP (User Datagram Protocol) on port 67 for incoming requests from clients and port 68 for client responses. This protocol allows devices on a network to automatically receive IP addresses and other configuration settings, simplifying network management.
It allows computers to "talk" each other in network.
