What is DHCP?

Dynamic Host Configuration Protocol or DHCP allows a computer to join a network without having a pre-configured IP address using the TCP/IP protocol. A computer needs an IP address to connect to the Internet.

The purpose of DHCP is to assign a dynamic IP addresses to a device on a network. Dynamic addressing means, a device can have a different IP address every time it connects to the network. In some systems, the IP address of the device or computer can even be changed while it is still connected.

Generally in case of Windows XP, Vista, Windows 7, Windows 8, users do not need to configure DHCP, as DHCP is often enabled by default and routers automatically assign an IP address to the computer.
