Your provider has used a RFC2317 scheme to delegate the reverse DNS to
you:
81.233.202.162.in-addr.arpa. 7200 IN CNAME 81.80/29.233.202.162.in-addr.arpa.
80/29.233.202.162.in-addr.arpa. 7200 IN NS ns2.archaxis.net.
80/29.233.202.162.in-addr.arpa. 7200 IN NS ns1.archaxis.net.
so you need
zone "80/29.233.202.162.in-addr.arpa." {
...
}
Btw, this diagnosis would not have been possible if you had obfuscated
the IP address. Thanks for being open, showing your real data,
allowing swift and easy help.
