Well yes and no. While an individual user would typically not,
resolvers sure will. While trying to resolve
250.199.212.125.in-addr.arpa, it will eventually get to
250.199.212.125.in-addr.arpa CNAME 250.0-24.199.212.125.in-addr.arpa.
Then it will need to resolve the canonical name, and a response like
the original one that was shown will be clearly buggy.
I say "possibly" because from my vantage, all three of
ns{,1,2}.viettelidc.com.vn, the authorities for
0-24.199.212.125.in-addr.arpa, are giving fine answers right now (on
udp; blocked on tcp). This includes the originally reported problem
IP, 115.84.177.8
