Title: DNS Question

Looks like the article defines several other syntax types (8-21, 8.21, etc.).  Maybe trying one of the other syntax will help.  Have you analyzed the traffic between client and DNS Server to see what information the client is providing?

But I can’t get it to work.

 

If I setup 8/21.203.10.in-addr.arpa and register a PTR record for 10.203.11.3 it creates a folder called 11 and places the PTR record of 3 in the 11 folder under the 8/21.203.10.in-addr.arpa folder but if you do a nslookup with the option setquery=ptr then you get a non-existent domain issue, even if you are doing a nslookup against the machine that holds the zone.

 

How does everyone else setup their reverse lookup zones when they used a subnetted ip schema?  Something other then 255.0.0.0, 255.255.0.0 and 255.255.255.0

 

Thanks

I was required to set this up on my external reverse look up zone since I was using a /26 subnet.  Of course these were not dynamic updates they were static.

 

I found this article from Microsoft http://support.microsoft.com/kb/q174419/ and it talks about how to create the zones.

Unfortunately and to the best of my knowledge, Reverse Lookup zones have no affinity to a given subnet mask.  The zone name that you created will never be used by any client to register their IP address/name because as far as a reverse lookup zone name goes it is malformed – the subnet mask in any form should not appear in the name.  To test this statement, manually create a PTR record in the zone and try to query for by using a “ping –a” command.

I am trying to create a DNS Reverse Look up zone for a subnet that has a /21 subnet mask.  Now how do I create just one zone?  I created the zone 8/21.203.10.in-addr.arpa on the Windows 2003 DNS Server but my servers are getting an error when trying to register DNS PTR Records.  Event ID 11160

Event Type:     Information
Event Source:   DnsApi
Event Category: None
Event ID:       11160
Date:           12/9/2004
Time:           11:03:25 AM
User:           N/A
Computer:       TCCHCCFP01
Description:
The system failed to register pointer (PTR) resource records (RRs) for network adapter
with settings:

   Adapter Name : {2107EBC8-41E4-4FD0-B090-7AA39B224864}
   Host Name : tcchccfp01
   Adapter-specific Domain Suffix : tcchcc.chcsnet.org
   DNS server list :
        10.203.11.1, 10.203.11.2
   Sent update to server : 192.175.48.1
   IP Address : 10.203.11.3

 The reason that the system could not register these RRs was because of a security related problem. The cause of this could be (a) your computer does not have permissions to register and update the specific DNS domain name set for this adapter, or (b) there might have been a problem negotiating valid credentials with the DNS server during the processing of the update request.

 You can manually retry DNS registration of the network adapter and its settings by typing "ipconfig /registerdns" at the command prompt. If problems still persist, contact your DNS server or network systems administrator.
