Re: [bitfolk] IPv4 reverse DNS

Hi Andy Smith,

I see many Andys replying here.

Yes I have at last realised this, from the other Andy's reply. In effect
the mailservers are following the Cname in the Bitfolk servers zone, so
they will not be looking for the shorter address. It makes perfect sense
now. What really puzzled me is that the zone file has sat like that for a
number of years just changing a little as it was added to, the old serial
number was from one of the later additions. Thank you for your time. That
example zone file you linked to is something I had obviously forgotten over
the years
