Comment 1 for bug 1599223

This will be fixed by adding A/AAAA RRsets for the interface names (first format above). If the second format (non-interface) is given to mod_authz_host, then either answer will work.

Having said that, this is actually a bug in mod_authz_host, which should grant access if ANY of the PTR RRset names matches the list of allowed hosts.
