Notes
Using special whois server
--------------------------
Some registrars can give special access to registered whois gatewais
in order to have more fine control against abusing the whois services.
The currently know whois services that offer special acccess are:
- ripe
The new ripe whois server software support some special parameters
that allow to pass the real client ip address. This feature is only
available to registered gateways. If you are registered you can use
this service when querying ripe ip addresses that way:
$whois = new Whois();
$whois->UseServer('uk','whois.ripe.net?-V{version},{ip} {query}');
$result = $whois->Lookup('62.97.102.115');
- whois.isoc.org.il
This server is also using the new ripe whois server software and
thus works the same way. If you are registered you can use this service
when querying .il domains that way:
$whois = new Whois();
$whois->UseServer('uk','whois.isoc.org.il?-V{version},{ip} {query}');
$result = $whois->Lookup('example.co.uk');
- whois.nic.uk
They offer what they call WHOIS2 (see http://www.nominet.org.uk/go/whois2 )
to registered users (usually Nominet members) with a higher amount of
permited queries by hour. If you are registered you can use this service
when querying .uk domains that way:
$whois = new Whois();
$whois->UseServer('uk','whois.nic.uk:1043?{hname} {ip} {query}');
$result = $whois->Lookup('example.co.uk');
This new feature also allows you to use a different whois server than
the preconfigured o discovered one by just calling whois->UseServer
and passing the tld and the server and args to use for the named tld.
UseServer can be called as many times as necessary.
