GNHLUGers

I am looking for an information resource that discusses command line utilities and how 
to use them to figure out network hierarchy, in the form of parent/child IP addresses.

I am hoping to be able to use these tools from inside a scripting language like Python.

In general I think the technique is:

        ping all the possible address on the network in question.

        For the responding devices do a traceroute, this tells you what devices cross 
networks.

        Use an SNMP tool to find out if the device is a managed switch or router,
                if so, get more info.

I have found tools that do the whole thing for you but I am interested in the process 
and how it works.  If I can find the info I am looking for I will use it to learn 
Python.

Thanks,

Jim McGlaughlin
