There's a problem when you use wildcards on IPv4 addresses:
*.0.0.2.zone.example.com
Matches IPv6 2.0.0.* (2.0.0.0/8), but it also matches IPv6 2000/12.
Any IPv6 address starting with "200", as many do.
By the way, the last paragraph of section 2.4 in RFC 5782 points out
this exact situation, so I hope it didn't come as a big surprise to
anyone.
