netmask question...

[Michael Scully]

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.
