What is DHCP?
To ensure that data from your computer always reaches the right target computer, such as a Web server, every connected computer connected to the internet has to have a identifier that is unique. This identifier is called the IP address. DHCP is a system increasingly used on networks whereby the IP address is allocated by a DHCP server as soon as you plug your computer into the network. The advantage of this is that if you move your computer
between different networks, say your home where you are connected to broadband, and the UCL Hall of Residence, you do not have to reconfigure your network parameters.
