Q1: Does a DNS rule for *.domain.com match multi-level domain names? In other words, if I just set *.domain.com in my DNS records, will it match all of:
a.domain.com
b.a.domain.com
c.b.a.domain.com
as many levels deep as needed, with just that one wildcard DNS specifier?
We have a use case for multi-level DNS and I would like to confirm that we are doing the right thing in setting one wildcard DNS setting for the root domain.
Q2: will this work with round-robin DNS?
