Dynamic Host Configuration Protocol (DHCP) is a standardized client/server network protocol that dynamically assigns IP addresses and other related configuration information to network devices. Every device on a TCP/IP-based network must have a unique unicast IP address to access the
DHCP stands for Dynamic Host Configuration Protocol. DHCP is used to control the network configuration of a host through a remote server. It comes installed as a default feature in most of the contemporary operating systems. DHCP is an excellent alternative to the time-consuming manual configuration of network settings on a host or a network ...
27 Σεπ 2024 · Dynamic Host Configuration Protocol is a network protocol used to automate the process of assigning IP addresses and other network configuration parameters to devices (such as computers, smartphones, and printers) on a network.
DHCP consists of two components: a protocol for delivering host-specific configuration parameters from a DHCP server to a host and a mechanism for allocating network addresses to hosts.
Message either unicast to h/w address of client or broadcast. Client should specify broadcast (through a flag bit) in any message to server if it cannot handle unicast before TCP/IP configuration. If ACK, make final check (for ex., is IP in use?). If no problem, do nothing. If problem, send DHCPDECLINE. ciaddr: Client IP address.
The Dynamic Host Configuration Protocol (DHCP) is the hidden magic that makes this happen. The protocol lets a DHCP client “lease” a variety of network and administrative parameters from a central server that is authorized to distribute them.
One of the primary tasks of the protocol is to automatically assign IP addresses to DHCP clients. A server running the DHCP service is called a DHCP server. The DHCP protocol automates the configuration of TCP/IP clients because IP addressing occurs through the system.
