It is not very famous trick. We can gather network interfaces through netbios as:

nmblookup -A 10.0.0.64
nmblookup -B 10.0.0.64 WIN7X64VM

querying WIN7X64VM on 10.0.0.64
10.0.0.64 WIN7X64VM<00>
12.0.0.1 WIN7X64VM<00>

Or the same with python:

from nmb.NetBIOS import NetBIOS # pip2 install pysmb
netbios_names = netbios.queryIPForName( "10.0.0.64", timeout=0.1 )
print ', '.join( (netbios.queryName( netbios_names[0], ip="10.0.0.64" ) or []) + netbios_names )

The script has been renamed to nbns-interfaces and committed as r38170, with the following tweaks:

  • The portrule is now restricting the execution to IPv4 scans.
  • If the target does not run NetBIOS server service, function netbios.get_server_name will return status true regardless but the returned name is nil. The script is now checking for this condition, instead of crashing.

Thank you for contributing to Nmap!
