So 'us.510.mail' is an atomic, arbitrary identifier. All three as a unit identify a certain node, and are selected purely for convenience of human operators, right? I'm just making sure that the network doesn't treat 'us.510.mail' any different than it would treat 'foobar', right? I was thinking in java/python mode, where each 'dot-level' actually pointed to a node in the network, while what I understand now is that once you go beyond the domain name, the way you handle the other nodes is just up to the sysadmin, and is purely for human readability, right? jm -- My other computer is your Windows box.
