Bruce: Sorry, I omitted your question as to what a netmask does. Netmasks are combined with the addresses to narrow the scope of broadcasts, and they define what IP network is your Local network. A typical class C network uses a netmask of 255.255.255.0, so that any other address with the same 3 xxx.yyy.zzz address will be part of your LAN. Any other address will be reached via your default gateway. When you create a static address, you specify the IP address, the netmask, and the default gateway. If you are using a DHCP server to do this automatically, all the settings are controlled by DHCP.
