Howto Combine Reverse Zones

[JohnSmith]

Hi,

I know this is a BIND shop, but I couldn't find anywhere else where the
people actually know what they are talking about.

I have in my reverse zones the following scenario.

10.1.1.x is a Standard Primary
10.1.x.x is DDNS
10.x.x.x is a Stand Primary

What I want to do is clean this up so that I only have one 10.x.x.x
zone and all the hierarchies beneath it, and make it an DDNS zone.
In my 10.x.x.x and 10.1.1.x zones I currently have a lot of static
configured entries and my 10.1.x.x zone has all the DDNS entries.

## Firstly: Is it a good idea, or should I leave it as is, and why.

##Secondly: How would I go about doing this, in a best practice kinda
way, as this is on M$2000 servers.

##Thridly: If they are merged into one zone, won't I stand the chance
of losing my static entries as it goes DDNS? or how can this be
prevented?

Thank you greatly in advance.
