Nettica offers classless reverse DNS services for IP address blocks ranging from 8 to 128 addresses. This service is not available to customers using dynamic addresses. With our reverse DNS service you control the Ptr records for your IP address block. In order for us to handle your reverse DNS, you must contact your ISP and have them delegate the reverse DNS lookups for your network block to our DNS servers (DNS1.NETTICA.COM, DNS2.NETTICA.COM, DNS3.NETTICA.COM, DNS4.NETTICA.COM, and DNS5.NETTICA.COM).

So who supports delegations to Nettica's servers?

Nettica does not endorse, or is endorsed by any companies listed. Not all ISPs supporting delegations to Nettica are listed. We do not accept delegations from any residential services, Verizon, or Qwest business DSL. Products and/or companies referred to herein are trademarks or registered trademarks of their respective companies or mark holders.

Their zone file setup would look similar to this:

0-29 IN NS DNS1.NETTICA.COM.
0-29 IN NS DNS2.NETTICA.COM.
0-29 IN NS DNS3.NETTICA.COM.
0-29 IN NS DNS4.NETTICA.COM.
0-29 IN NS DNS5.NETTICA.COM.
;
0 IN CNAME 0.0-29.1.168.192.in-addr.arpa.
1 IN CNAME 1.0-29.1.168.192.in-addr.arpa.
2 IN CNAME 2.0-29.1.168.192.in-addr.arpa.
3 IN CNAME 3.0-29.1.168.192.in-addr.arpa.
4 IN CNAME 4.0-29.1.168.192.in-addr.arpa.
5 IN CNAME 5.0-29.1.168.192.in-addr.arpa.
6 IN CNAME 6.0-29.1.168.192.in-addr.arpa.
7 IN CNAME 7.0-29.1.168.192.in-addr.arpa.
