Reverse DNS setup


D

Dave

I host my own DNS server and I want to setup reverse DNS.
When it ask for Network ID #. I'm not sure what to put
in. I have my ISP internet IP(24.8.76.48)that runs on my
gateway router or my internal server IP (192.168.0.95)
that runs NAT?

Thanks for your help
Dave

Hello Dave,

Please look at the reverse lookup zone creation section in the following
article:

308201 HOW TO: Create a New Zone on a DNS Server in Windows 2000
http://support.microsoft.com/?id=308201

From your network description below, if your subnet mask in 255.255.255.0 on
the internal
server IP, then the network ID will be "192.168.0."

Hope that helps!

Dave,
If you are refering to a reverse lookup on a public IP it will have to be
delegated to you by your ISP. If the IP you posted is your actual IP that
address belongs to Comcast and I can almost guarantee you that they won't do
it.
There is a reverse lookup on the IP now (see below) you might get them to
change the PTR.
How I am searching:
Asking f.root-servers.net for 48.76.8.24.in-addr.arpa PTR record:
f.root-servers.net says to go to dill.arin.net. (zone:
24.in-addr.arpa.)
Asking dill.arin.net. for 48.76.8.24.in-addr.arpa PTR record:
dill.arin.net says to go to dns01.jdc01.pa.comcast.net. (zone:
8.24.in-addr.arpa.)
Asking dns01.jdc01.pa.comcast.net. for 48.76.8.24.in-addr.arpa PTR record:
dns01.jdc01.pa.comcast.net says to go to ns4.attbb.net. (zone:
76.8.24.in-addr.arpa.)
Asking ns4.attbb.net. for 48.76.8.24.in-addr.arpa PTR record: Reports
c-24-8-76-48.client.comcast.net.

Answer:
24.8.76.48 PTR record: c-24-8-76-48.client.comcast.net. [TTL 86400s]
[A=24.8.76.48]
