you can of course define 168.192.in-addr.arpa and put everything there.

the problem above looks like client with IP 192.168.16.3 asked the 
named on server mail2 for 108.21.168.192.in-addr.arpa and 
171.1.168.192.in-addr.arpa and got the responses from the internet.
You should serve those zones locally...
