how to archieve this?

[ivan jr sy]

refer to 'split' DNS using views

here's something:

in a nutshell.. you have to
- have 2 views, same zone per view
- either have two different zone files... and maintain it separately. (or you may have two zone files and segregate the differences, while those RRs that are common can be on another file referred by an include statement)
