Normally if you have a cable modem or DSL, you get your home PC's IP address dynamically assigned from your service provider. if you install a home cable/DSL router between your modem and home network, your PC will most likely get its IP address at boot time from the Home Router instead. you can choose to disable the DHCP server feature on your home router and set up a Linux box as the DHCP server. This cha
