how to change FQDN of a reverse-zone


S

Steffen Meier

Hi,

I have to publish a PTR for our email-server.
The IP Nr of our email Server is 192.159.181.251.
(w have a public IP-Rang with 128 Ip-Nr, starting from 192.159.181.128 to .
255)

I have created a reverse-zone using the DNS wizard, here is how it looks
like in the DNS-Console view:

128.181.159.192.in-addr.arpa
251
181
159: here I added the PTR with name 192
Properties of that PTR are:
Host IP-Nr: 192
FQDN: 159.181.251.128.181.159.192.in-addr.arpa
Hostname: gw.domain.com


According to my provider, the reverse-Lookupzone is OK.
The problem seems to be the FQDN 159.181.251.128.181.159.192.in-addr.arpa
My provider told me to change the FQDN to 251.128.181.159.192.in-addr.arpa.
However - the FQDN was created by the wizard while creating the
reverse-zone - and I can not edit it.
Is there a way to change the FQDN manually ?

Thank you

Steffen

Delete everything below this and create your PTRs in this zone. When
combined with the CNAME delegations it will work.
E.g. PTR named 129 reverses to 129.128.181.159.192.in-addr.arpa.
This would be much easier to diagnose if you gave the actual IP range.

Take a look at my delegated zone, 208.91.65.65.in-addr.arpa. my PTR is
209.208.91.65.65.in-addr.arpa. which is a CNAME at my ISP for
209.91.65.65.in-addr.arpa.

delete> 251
delete> 181
delete> 159: here I added the PTR with name 192
