It should be:
11.22.33.44.in-addr.arpa. cname 11.14/28.22.33.44.in-addr.arpa.

You need to have NS records for 14/28.22.33.44.in-addr.arpa:
14/28.22.33.44.in-addr.arpa. IN NS otherserver1.otherdomain.com.
IN NS otherserver2.otherdomain.com.
It doesn't matter at all what subnet the server is on.
This is all explained in RFC 2317 and in the DNS & BIND book. Just copy
their examples and you should be fine.
