Every device that connects to a network needs an IP address. Network administrators assign static IP addresses to routers, servers, and other network devices whose locations (physical and logical) are not likely to change. Administrators enter static IP addresses manually when they configure devices to join the network. Static addresses also enable administrators to manage those devices remotely. However, computers in an organization often change locations, physically and logically. | I 1111111.

Network administrators assign static IP addresses to routers servers and other network devices whose locations physical and logical are not likely to change. Administrators enter static IP addresses manually when they configure devices to join the network. Static addresses also enable administrators to manage those devices remotely. However computers in an organization often change locations physically and logically. Administrators are unable to keep up with havingto assign new IP addresses every time an employee moves to a different office or cubicle. Desktop clients do not require a static address. Instead a workstation can use any address within a range of addresses. This range is typically within an IP subnet DHCP assigns IP addresses and other important network configuration information dynamically. Because desktop clients typically make up the bulk of network nodes DHCP is an extremely useful and timesaving tool for network administrators. RFC 2131 describes DhCP.
