LAN

Local Area Network

You have more than one host on your local network.

A simple home example is as soon as you have two or more computers you want to share the internet connection with, you will need to create a LAN. Every host will need its own IP.

You can use an RFC 1918 address, which were created specifically for private addressing, so you can play as you wish on your home network.

10.0.0.0 – 10.255.255.255 (10.0.0.0/8)

172.16.0.0 – 172.31.255.255 (172.16.0.0/12)

192.168.0.0 – 192.168.255.255 (192.168.0.0/16)

Technically you can use any IP you want, including public IP space, however it is recommended you keep it adequately firewalled if you follow this route, as you will probably be mimicing valid IP addresses which are trying to function on the internet.
