Need to manage multiple zones in DNS

rsmccain · 09-06-2007, 01:07 PM

Lets say I have domainA.com, domainB.com and domainC.com. I want to be able to make record entries in domainA.com and have it sync/mirror to the other domains.

The reason for this is we are in the process of migrating from one domain to the others.

A co-worker mentioned using DNAME record(s) but I've been reading around and it seems that its very popular with the BIND community.

Any suggestions?

I think there are scripts that can build the named files for you, though I don't know anything about the DNAME stuff, except with connecting it to DHCP. I don't think that's what you're wanting to do though.

So, a script that took a list of DNS names, and built the named files, with a new serial number, and is run manually after the new name added, or existing name modified or removed.

I'm sure some exist... can't think of one off the top of my head though.

Any idea where these scripts might live?

somewhere on the big blue internet

I just tried a quick internet search, but didn't find anything.

There are a number of web based management interfaces... Don't know if that would be a better solution?

DNAME is a option.

You can also have multiple zones using the same file in named.conf. You just need to make sure you use the shortcuts in the zone and don't define the actual domain in the zone file. Also sym links can be used that just refer to the "master" file.

For example instead of using this in the SOA

Code:

yourdomain.com.     IN     SOA     ns1.yourdomain.com.     support.yourdomain.com. (

use,

Code:

@     SOA     ns1     support (

Same goes for your resource records

Code:

host56.yourdomain.com.        IN    A     192.168.0.10

replaced with

Code:

host56        IN    A     192.168.0.10
