DHCP (Dynamic Host Configuration Protocol) loans (leases) a unique IP address from an available pool, which is set at the server, to a client machine for a period of time. Beyond IP addresses, DHCP can assign DNS and WINS servers, as well as routing information such as the default gateway and subnet mask. DHCP is BOOTP compatible.
One thing to watch out for is that you can set each adapter on your system (including both LAN adapters and dial-up adapters used to contact your ISP) to get TCP/IP configuration information from a central server on the network via DHCP.
It can happen that you are working away busily on your LAN connection, then dial out to your ISP and find that you can no longer access any LAN computers by name this might occur if when you dialed out, your dial-up networking connection replaced your DNS server setting with one that points to an Internet-based DNS server. If your internal LAN hosts are private and are not listed in DNS on the Internet, these hosts would all of a sudden become unreachable. One way to check if this is the problem youre experiencing is to disconnect from the dial-up connection, and then see if you regain access to local computers by name.
