This includes the transport delay. The value is normally given in milliseconds.DHCPDynamic host configuration protocol. DHCP is a communications protocol that lets network administratorsmanage centrally and automate the assignment of IP addresses in an organization's network. Using theInternet Protocol, each machine that can connect to the Internet needs a unique IP address. When anorganization sets up its computer users with a connection to the Internet, an IP address must be assigned toeach machine. Without DHCP, the IP address must be entered manually at each computer and, if computersmove to another location in another part of the network, a new IP address must be entered. DHCP lets anetwork administrator supervise and distribute IP addresses from a central point and automatically sends anew IP address when a computer is plugged into a different place in the network.IPInternet Protocol.
