I am not sure you can with the Samba tools, I think you will need to 
query each record individually.

That is strange, first thought is that it is possibly a Windows bug, if 
anything Windows should refuse to show any IPv4 address with more than 4 
octets. Have you tried checking the records in AD with ldbsearch ?
