What changes when there is a zone cut (delegation) rather than having
sub-subdomains all in the same zone? Controlling inheritance obviously has
different tastes depending on the case. Which case is more common?
If it’s a zone cut, then that supports the “bottom-most” policy even more than
if it’s in the same zone, IMO.
For clarity, let me point out that bottom-most refers to the convention that
abstract trees have their roots at the top. IOW, since ret.bmcc is in the same
zone as bmcc it seems better for the former to inherit from the latter than
from its org domain.
However, in that case both zones are under the same master server:
cuny.edu. 2801 IN SOA acme.ucc.cuny.edu.
hostmaster.acme.ucc.cuny.edu. 2019022032 3600 1800 2419200 3600
bmcc.cuny.edu. 300 IN SOA acme.ucc.cuny.edu.
hostmaster.acme.ucc.cuny.edu. 200804826 300 3600 2419200 3600
ret.bmcc.cuny.edu. (no SOA)
(Those funny serials cannot begin with the year. We had no DMARC in 2008.)
Best
Ale
