Any WTF did it work for me the last couple of months on another machines with the proper netmask then? Remember: documenting a bug doesn't fix it (else MS soft would be much more stable....) But the above isn't correct. It strikes me for any two IPs from the same subnet, not only for such that are in the same subnet as the first one.
