Zone Transfer issues

Is there a way to do an incremental zone transfer for the reverse zones between a BIND 9 server and a Windows 2003 server.

Here is the layout
Windows 2003 server
CompanyA.com
10.in-addr.arpa

Bind 9 server
CompanyA.net
10.in-addr.arpa

Can I combine both reverse zones into one big reverse zone on the windows server?
I need to maintain both servers, so moving off of the Bind server is not an option

Thanks for the assistance.

Well I'm not precisely sure they will use incremental transfer (it's likely), but they will most certainly allow zone transfers between them.

I don't know how to configure Microsoft DNS Server to be a slave, but this is an example of how to make the BIND server a slave to the MS server.

zone "10.in-addr.arpa" IN {
type slave;
masters { 10.0.0.1; } # IP of MS dns server
file "slave/10.rev";
};

Both servers need to be master of thier own address spaces. The .net server has IP addresses in the lower 15 and the upper 15 addresses. The .com server has the rest of the addresses. I would try to sub-zone them, but there are more than 45 different IP ranges.

Ok, so you weren't complete in describing the problem in your first post. And then you gave me another piece of your puzzle in your second post. Please reexplain your problem with all the pieces put together. Make sure to fully describe the configuration you have right now, and the configuration you want to have. Also explain what you mean by "upper 15 addresses". I don't know the size of your network or the ranges you are putting to use. For all I know you mean the upper 15 addresses in the 10.0.0.0/8 network, or you could mean the upper 15 addresses in the 10.0.0.0/24 network. Upper 15 may mean the upper 15 bits in the address, or it may simply be x.x.x.240-255.

The more information you give me, the more likely I can help you. Sure, maybe I have a better idea now what you need, but neither you or I want to play the guessing game cause it wastes our time if I guess wrong. So I'd rather that you start back at the top.

Ok, I was in a hurry when I entered the first post.
Here is the configuration and the issue that I have.
Private network addresses from 10.200.1.1 to 10.200.232.254 and everything in between.
My department manages the internal DNS for our Windows/Unix servers and workstations. The other department manages the network equipment DNS (routers and such).


Everything in the company sits somewhere in the 10.200.xxx.xxx address space. Servers and workstations are managed by DNS on a Windows NT 4.0 platform (this will be moving to windows 2003 shortly). Network equipment is managed by BIND 9 DNS. The NT 4.0 server holds the primary zones for CompanyA.com and 10.in-addr.arpa, I manage all of the DNS information on the windows server.
The other department handles the CompanyA.net zone as well as thier own 10.in-addr.arpa for all of the network equipment.
I get zone transfers for CompanyA.net from the BIND server, but I cannot seem to get the reverse information added to my reverse zone.
Ultimately, what I would like to do is get zone updates from the BIND server into my reverse zone file without having to rewrite everything with custom apps.
I hope this explains better what I am trying to get done.
Thank you for your time.

Ok, that definately helps. Now I'm down to only 2 possibilities as to what you are wanting to achieve.

1) You want to literally combine both 10.0.0.0/8 zones into one file and assume full responsibility or share full responsibility for both .com's and .net's reverse IP pointers.
2) You want to continue to manage the .com addresses only, yet also host the .net addresses on your server as configured on the BIND server.

Based on previous posts, I'm guessing that you want to accomplish #2. Also based on previous posts I'm guessing that these are your network ranges:

Networks in CIDR Format:

And repeated for 10.200.1 and 10.200.2 etc.

What a mess man. My best suggestion is a script generating a list of network subnets which perform as master or slave depending on whether they fall under NET or COM. I know that BIND supports subnetting, but I don't know enough about Microsoft DNS Server to know if it'll support it. BIND also has some interesting limited generation script capabilities which could make things easier on the BIND side of things.

You are correct.
I need to Host the .com address as well as be a secondary for the .net addresses. This part works so far.
The issue is for the reverse lookups. I host the reverse zone, but need to add to it the addresses from the .net zone. If I do a zone transfer from the BIND server for the reverse file, I must do a complete transfer, loosing my original reverse zone file.

Well well, I see clearly now. You have the wrong idea on what incremental transfer is all about. You need to edit the zone contents on the BIND server for .NET addresses. You can do this remotely using the Microsoft DNS Manager (I think) if you just enable dynamic support to the BIND zones.
