Hello:

I need to configure a subnetted reverse DNS zone on my Internet DNS servers.
I am running Windows 2003. I thought I did it correctly but the the subnet
is throwing me off. Can and one give me some advice on this.

208.5.55.0 255.255.255.192

Thanks

Harrison

create a DNS zone with the name: 0-26.55.5.208.in-addr.arpa

or

DNSCMD.EXE /ZoneAdd 0-26.55.5.208.in-addr.arpa /Primary /file
0-26.55.5.208.in-addr.arpa.dns


for more info have a look at the article Ace gave you. However, dynamic
updates are not possible. You must add PTR records manually.

Curious, have you tested that?

the article (http://support.microsoft.com/?id=174419) says:
"Note Dynamic updates for subnetted reverse lookups do not work in Windows
2000. The records will need to be added manually. Using "Create Associated
PTR record" checkbox will not work for the subnetted reverse lookup zone
when "A" (host) record is created through GUI"

the article
(http://www.microsoft.com/technet/pro....mspx?mfr=true)
says:
"Dynamic update does not work with classless in - addr.arpa zones. If you
need to dynamically update PTR resource records, do not use classless zones"

I have submitted an proposal to update the first article to:
"where the note is changed to:
Note Dynamic updates for subnetted reverse lookups do not work in Windows
2000 Server and Windows Server 2003. The records will need to be added
manually. Using "Create Associated PTR record" checkbox will not work for
the subnetted reverse lookup zone when "A" (host) record is created through
GUI"

I found out when doing some tests in w2k3sp1. It did not create the PTR
record until I created classfull dns zones (8, 16 or 24 bit)

I hope it gets published. I don't see why not. It would make sense for an
article like that to be more specific.

I read that part in the article, but was curious whether you actually tested
it. I have created reverse zones, but they were only for delegated reverse
zones for external data and not for internal, hence never found a reason to
test it or even use dynamic updates on such zones.

Thanks Jorge,

Ace

If this is the actual subnet, you will have to contact your ISP. This subnet
authority belongs to Sprintlink, which does not usually create PTRs, and
I've never known them to delegate. I'm not saying they won't delegate, I
just don't know any cases when they have, and I had several cases from other
users using Sprintlink. In the previous cases I've handled, Sprint just
created the PTRs.

The point of this is, you can create all the reverse lookup zones you want
for this subnet on your DNS servers, and public queries won't get to them
until the delegation is done. If you can get the delegation done, you must
use the exact zone name in the delegation, there are several ways to
delegate reverse zones.
