[ILUG] network discovery...

[John Malone]

Could you use nslookup?

For example...


 me at host > nslookup 

 > server ns1.mit.edu
  Default Server:  W20NS.MIT.EDU
  Address:  18.70.0.160
  Aliases:  ns1.mit.edu

 > ls mit.edu
 
 [lots of mit hosts follow...]


You can also pass args to ls to tell about the hardware on the network.
Interesting reading if your quite, quite bored... 


Note: This will give you in the region of 65,000 hosts (I think) so use
with caution, on mit anyway.
