Ifconfig does not work on Windows. Are you saying that there are other operating systems brain-dead enough to just run any old arbitrary code from untrusted media?

The good news is one 'ifconfig' just tells them what network address you're in. Unless the attacker can gain access to your host's NDP table or ARP table, they can't see what IPs are in use.
All it takes is one USB stick left out in the parking lot for an employee.. By the time they get enough access to do an 'ifconfig', rest assured that they can see the NDP/ARP tables and all the traffic on that network segment as well. (OK.. maybe for some reason they can't - but if you're betting your security model on somebody getting a beachhead on one of your machines and *not* having full access to the network segment, I'll be more than happy to take the other side of the bet).
