The known hostnames "localhost", "*" and "127.0.0.1" (and "::1" for IPv6) are
guaranteed to be localhost and you could even hardcode that. However, there
are other several possibilities of loopback that won't show up unless you
perform a lookup.
That is the case for "localhost.localdomain" and any other "localhost.*" that
will show up only by reading /etc/hosts and DNS queries. If that is
acceptable, I think we could add a member (static?) function isLocalhost() to
KInetSocketAddress that would return true in case an address is localhost.
However, this would be a new feature...
PS: that would probably be best in KAddressInfo or in the proposed
