PTR a.node.on.vlan344.namn.se. ...will work just fine, for instance.Since there is no AAAA record for a.node.on.vlan344.namn.se., this won't work fine in any rDNS check I'm aware of.
it works just fine, as long as there is one AAAA for that name (even in a different netblock), and -that- adderess has rDNS matching the AAAA
You are aware that useful rDNS has to have matching forward DNs, right?
"Not exactly." <grin> The 'usual' test is 'rev->fwd-rev' and compare the results of the two 'rev' look-ups. This allows a host with multiple interfaces to have -one- name for all interfaces.
