What is DHCP? What IP addresses should I use?
A. – Before computers on a network can talk to each other they need to be able to identify each other, and for this they need to have an IP address. An IP address is four numbers, all between 0 and 255, separated by dots. All computers on the internet have a unique IP address. There is a range of IP addresses set aside specifically for LANs, they are of the form ‘192.168.xxx.yyy’. You can use any numbers you want instead of xxx and yyy as long as all the computers on the network have a unique address (though it is recommended that you use the same xxx number for all of them, otherwise the computers won’t be able to see each other). In order to alleviate the hassle of setting each computer’s IP address individually you can use DHCP (Dynamic Host Control Protocol). One computer on your network is the DHCP server and this supplies all the other computers with a unique IP address when they connect.
