No, it's 22.214.171.124/28. The number after the slash is the number of
1-bits in the network mask. Also, your range ends at .223, not .224.
It looks like the created the delegation; you can see it with:
dig -x 126.96.36.199/28 ns @nameserver.concentric.net
However, they haven't created the CNAME records for
188.8.131.52.in-addr.arpa through 184.108.40.206.in-addr.arpa. If you do:
dig -x 220.127.116.11 any @nameserver.concentric.net
you won't see the CNAME record that should be there.
