[ Cross-posted to comp.sys.att and u3b.tech - followups directed to 
  those groups only, since this is probably getting too 3B2-specific ]

The version of "ifconfig" that came with our WIN TCP/IP (version 1.0) does
not offer "netmask" as a valid option. Do more recent versions support it?
Is the lack of a netmask option a hardware or software limitation? Will an
upgrade of the WIN TCP/IP help?

I just recently became interested in this stuff, so I'm looking for answers
rather than supplying them. Our department is moving to a new building in a
couple of weeks (where we will have to use sub-nets), so I have suddenly
developed a rather pressing need to solve this problem. Any help would be
appreciated.
