The simplest approach is to enumerate and ping each and every address in
your subnet and wait for the response, but consider that some hosts may
have been configured to not answer (and assuming you don't have a /8
network...)
There is an ICMP library in the Python cookbook
http://aspn.activestate.com/ASPN/Pytho... and you can search the
Package Index too: http://pypi....

Do you mean, you have a router device, and you want to ask it for its
routing tables? This has other problems too: depending on the network
topology, the router may not even know about some hosts, or they may have
disconnected and the router didn't notice...

If you have a running DNS, surely you can query it. But this doesn't tell
you about "connected" hosts as you said earlier.

More than a Python question, this is a network management question. There
are a lot of applications that can help; try something based on SNMP
