Missing a trailing period(.)
Here's a fun trick to avoid making this mistake: use FQDNs everywhere in
the zone file, and use the directive
$ORIGIN .
so that it doesn't matter whether you have the trailing . or not.
Downside, of course, is that you have to repeat your domain name about a
gazillion times.
scripting is the better answer
our toolset just would have added to "ns1.mail.lab.example.com" at final
dot because it contains more than one dot like it would to with
"mail.exmaple.com" while "mail.example" would not get touched sicne it's
clearly a subdmain
how often do you have "sub.sub.sub" within a zone and how often it's a
external server - if you really need "sub.sub.sub" then you are require
to type it full-qualified including the domain name, well and then the
final dot is added again automatically - that don't happen that often
and if you have a larger subdomain that deep just maintain it in a own
zone file
that is catching real life for many years now and generates complete
zone files out of a simple database with a small webinterface
