In this case, the answer is that your main zone (example.com) will
have an error, because it will have an A record below the "bottom" of
the zone that is not a glue record. In other words, it will recognize
that www.my.example.com belongs to my.example.com, not to
example.com.
Chris,
You said main zone will get an error b/c it has that an A record below
the bottom of the zone.
Is it correct if that A record was on the top of the zone? like:
www.my.example.com. IN A 11.22.33.44
my.example.com. IN NS ns.my.example.com.
ns.my.example.com. IN A 55.66.77.88
No, I didn't mean positionally within the zone file. Record order is
mostly irrelevant in zone files (but the SOA record must be first).
The "bottom" of a zone is any delegation point to a subzone. "www.my"
is below a delegation of "my". The exception is glue records, which
are address records that belong to the subzone but are present to
support the delegation itself.
