How to deny update of statically assgined a/ptr records?

[Oleg Gvozdev]

Hello.

I have dynamic zone. And A record in it:

Example(pseudo-code):


*zone myzone.*
*  a 10.0.0.1 domain xxx*

Then I made DHCP update for host "host.myzone." and it receives address
from dynamic range (10.0.0.10-10.0.0.100), for example: 10.0.0.10.


So host.myzone. has 2 A records: 10.0.0.1 and 10.0.0.10.

How I can configure BIND to deny updating records (for example A/PTR) for
hosts, that already have static A/PTR records in DNS zone ?

Thanks.
