SPF for IPv6

Shouldn't we have SPF records for IPv6 ? Example: I got a default ipv6 from datacenter. Never used it. No in hostname or anywhere. But sending email to check-auth@verifier.port25 I get a result like: ========================================================== Original Email ========================================================== Return-Path: Received: from myserver (xxxx:4f8:192:21d2::) by verifier.port25.com id hc5puu11u9cq for ; Fri, 18 Oct 2013 13:46:23 -0400 (envelope-from ) Authentication-Results: verifier.port25.com; spf=fail (not permitted) smtp.mailfrom=xxx
it tries to check SPF record for the ipv6 address. But cPanel doesn't add something like that. ---------------------------------------------------------- SPF check details: ---------------------------------------------------------- Result: fail (not permitted) ID(s) verified: smtp.mailfrom=xxxx DNS record(s): xxxx.com. SPF (no records) xxxx.com. 1800 IN TXT "v=spf1 +a +mx +ip4:x.x.x.x +ip4:x.x.x.x -all"

  You can add SPF record for IPv6 in your domain zone by adding ip6:IPv6-range to the TXT line.
