GNU/Linux Desktop Survival Guide

During an install DHCP will be attempted to obtain your network information from a DHCP server. This (usually) requires that you identify your host as a host that your DHCP server knows or relies on the DHCP server allocating the next available IP address. Do so just to see if there is a DHCP server available to you.
If a DHCP server is not available then you will be prompted for alternative options, including manually setting up the appropriate network information.
Generally you need the following, where some sample addresses are
IP 184.108.40.206 Netmask 255.255.255.192 Gateway 220.127.116.11 Domain togaware.com DNS 18.104.22.168
The information is recorded in /etc/network/interfaces and /etc/resolv.conf. Later on edit /etc/resolv.conf to add search togaware.com so that you can refer to your local machines by their name, without fully specifying the domain.
Some useful commands for trouble shooting are:
# netstat -n # ifconfig -a
