JM> AFAIK, a fully qualified domain name is like JM> machine.domain.xxx JM> but what about addresses like JM> us.510.mail.yahoo.com?? JM> Is there any hierarchy to the names in this case? JM> jm --------------------------------------------- I would think that viewing mail.yahoo.com as machine.domain.xxx might be flawed if you think of mail.yahoo.com as subdomain.domain.top-level-domain it is (or so I think) easier to comprehend that subdomain.subdomain.domain.top-level-domain is not that different. Now add to that picture that every subdomain could be an alias for another domain or point to an IP address, which incase of the IP address is meaning a real machine. Did I misinterpret your question ? Hexren
