  Here you got it wrong.  IPv4 reverses are split at octet boundary, you
cannot have greater granularity.  And for sure you cannot mix CIDR addressing (/28)
and netblock type.  On top of that, “/” is not correct character in DNS.

   Your reverse zone is 10.5.10.in-addr.arpa. 

(IPv6 reverses are split at nibble boundary, FWIW).
