I am not too sure about .255. I have used nodes that was assigned that address and it worked. Perhaps it has something to do with the broadcast address and supernetting. I don't know but some organization assign this address via DHCP with no problems. Perhaps someone can explain why or how this works with xxx.xxx.xxx.255 is the ip? jay -- Your login is not in the sudoers file. This incident will be reported!
