DHCP is built on a client-server model, as follows: The DHCP server hosts allocate network addresses and deliver configuration parameters, the term "client" refers to a host requesting initialization parameters from a DHCP server. Inviting you to refer lecture for more infomation. | DHCP AND ARP Understanding DHCP DHCP is built on a client-server model, as follows: The DHCP server hosts allocate network addresses and deliver configuration parameters. The term "client" refers to a host requesting initialization parameters from a DHCP server. DHCP supports these three mechanisms for IP address allocation: Automatic allocation; DHCP assigns a permanent IP address to a client. Dynamic allocation; DHCP assigns an IP address to a client for a limited period of time. Manual allocation; A client IP address is assigned by the network administrator, and DHCP is used simply to convey the assigned address to the client. Dynamic allocation is the only that allows automatic reuse of an address that is no longer needed by the client to which it was assigned. DHCP Using a Router as a DHCP Server Cisco IOS Software includes a full DHCP server implementation: Assigns IP addresses from specified address pools within the router Can be configured to assign the IP address of these . | DHCP AND ARP Understanding DHCP DHCP is built on a client-server model, as follows: The DHCP server hosts allocate network addresses and deliver configuration parameters.
