Description: ------------ In 2010, IPv6 spam accounted for almost 2% of all spam. * http://labs.ripe.net/Members/blazquez/content-spam-over- ipv6 This is significant enough for a DNSBL for IPv6 to exist. * http://virbl.bit.nl/ There are examples on how to use "virbl.bit.nl" with email servers, but not programmatically. IPv6 is quite different to IPv4, since IPv6 is separated using a colon rather than a "dot". It is not possible to put a colon (:) in a hostname, so the current methodology could not be used. IE: Dns resolved 2.0.0.127.cbl.abuseat.org to 127.0.0.2 I have contacted virbl at bit.nl to see what they propose. This will form the start of development for IPv6 support in DNSBL.
