Vu,

You really can't. At least not unless it's been added since the version
I've got (2.1.6). The problem is that there's no way to enter a
netmask. You are prompted only for an IP address. The ip_discover.tcl
code parses this and determines if it's a class A, B, or C network, and
then proceeds to probe that entire network address space. This would be
relatively easy to fix by modifying ip_discover.tcl. Just add a prompt
for a netmask and use that to determine which addresses to probe.
(Again, I'm only looking at 2.1.6, I'm sure someone will correct me if
this has already been changed in a newer version.)
