DHCP
DHCP (Dynamic Host Configuration Protocol) is a technique used in W95/W98/Me/NT/W2K/XP/W2003/Vista/W7-32/W7-64 for dynamically assigning IP (Internet Protocol) numbers. A DHCP server assigns IP numbers for a temporary period. They also automatically assign some DNS servers, telling you the IPs to use. The magic of DHCP is that workstations don’t need to know the IP of the DHCP server to get started. PPP has a similar mechanism to dynamically assign IP numbers for dial up calls. DHCP is commonly used for 24/7 cable modem access. DHCP is primarily for convenience rather than to allow IPs to change frequently. With DHCP, nobody has to assign numbers to individual workstations and configure them individually. All machines are set to DHCP IP assignment. They automatically find themselves a free IP when they are turned on, with the help of a DHCP server. The secondary reason for using DHCP is to make maximal use of a small pool of IP numbers when you have more users than IPs available.

DHCP servers in my experience tend to be somewhat flaky. You can cheat and set the IP it keeps giving you as a permanent IP. If you don’t use DHCP, you must also manually configure some DNS (Domain Name Service) server IPs. If anything goes wrong, revert to DHCP, reboot, and pray the DHCP servers are up.

You can also clear its pea brain with:

When you have a router you can use static or DHCP IP assignment for for your computers to talk to the router and for the router to talk to your IAP (Internet Access Provider).
