unknown host

Author: J.McKay2 (13 Aug 13 1:31am)

Hi,

I am trying to use the api from a java app and am getting unknownhost exception when I try and resolve: my12charakey.98.228.142.83.dnsbl.httpbl.org (have removed my key in all that follows)

The reversed ip is arbitary but exists. Other lookups like say google.com work fine so I think my dns config is ok.

In java the code is very simple:

InetAddress ia = InetAddress.getByName("my12charakey.98.228.142.83.dnsbl.httpbl.org");

have also tried:

InetAddress ia = Inet4Address.getByName("my12charakey.98.228.142.83.dnsbl.httpbl.org");

Any thoughts on what might be the problem would be much appreciated !!

Many thanks.
John
