Answer all named requests with same ip

I need either a simple modification to a existing name server or a simple solution that does the following. 1) for each nameserver request that comes in it will check the normal zones and give a answer like usual. 2) If the domain exist in the zones instead of failing it will give a fixed answer which will be definable by me in a config file. This can be a easy fix to named or even a perl program that always answers with the same answer. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform This would operating on freebsd/linux
