It shouldn't be in the "ip" namespace either.

The name translation service in any modern operating system can return 
address objects for any network families it supports.

In practice, getaddrinfo can return addresses for IPv4 and IPv6. There 
is no reason why it can't return addresses for any other kind of network 
(unless naming objects in that network is radically different from 
"host"/"service").
