Ok, it's just that every program/service that uses IPv6, seems to leave the IPv6 tag in tact. I'll leave it to Julian.

It's important for ACL I think, since you need to know what to match against.

I've done some tests with "(?:Ipv6:)?", but that only works for IPv4, no longer for IPv6. This is what I used for testing:

****************
#! /usr/bin/perl

$ip = "$_xs6.xs4all.nl [IPv6:2001:888:0:1::666]";
#$ip = "$_smtp.jiscmail.ac.uk [130.246.192.55]";

if ($ip =~ /\[(?:Ipv6:)?([\d.:abcdef]+)\]/) {
  print "match\n";
  print "$1\n";
} else {
  print "no match\n";
  print "$1\n";
}
****************

Anyway, Julian will hopefully shed his guru perl light on the problem and a proper fix! ;-)
