Andreas Fischer ed44235d26 [ticket/9534] Adding support for IPv6 addresses in user_ipwhois().
whois.arin.net does currently not refer to other servers (using ReferralServer)
when queried for an IPv6 address. whois.sixxs.net however works in this case.

This also adds '.' to the hostname to make sure we're querying the dns root.
