CNAME point on record with multiple A/AAAA addresses
I don't know if this is a standard from RFC.
If I have CNAME which point on a record with multiple A/AAA addresses, e.q.:
a.example.org. IN A 1.2.3.4
a.example.org. IN A 5.6.7.8
b.example.org .IN CNAME a.example.org.
I would expect answer:
b.example.org. IN CNAME a.example.org.
a.example.org. IN A 1.2.3.4
a.example.org. IN A 5.6.7.8
But resolver returns me only one A record (always the first):
b.example.org. IN CNAME a.example.org.
a.example.org. IN A 1.2.3.4
Other resolvers (bind, unbound) returns me both A records. The behavior is the same for multiple AAAA records.
