Reverse DNS service is a premium service of Nettica Corporation and
is not bundled with any of our other services. Reverse DNS is a
business-class service available to customers with a block of static IP
addresses. Reverse DNS service adds credibility to your Internet presence
and is becoming ever more important in the fight against unsolicited
email. Major ISPs have begun blocking email servers that do not have a
proper reverse DNS record setup.
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?
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.
This is a fictional example of an ISP's zone file setup for the 192.168.1.0/29
address block.
