Can we verify the DNS response

An entry in the bb-host file like:

 

192.168.10.10     bambam              # dns=fred

 

will perform a DNS query against the server bambam for the hostname:
fred.  The way I understand it is if a response is received, the DNS is
considered good.

 

I would like to know if here are any options to verify the result.  In
my particular case, we want to query against a "Split DNS" server and
confirm the correct IP is being returned in the A record.  So,

 

192.168.10.10     bambam.dom.com                         #
dns=fred.dom.com

71.137.200.10     bambam.dom.com                         #
dns=fred.dom.com

 

The first entry should return:  192.168.10.15

The second entry should return: 71.137.200.15

 

If DNS views are broken, the 2nd entry may return:  192.168.10.15   If
so, I want to get a page so DNS can be fixed.

 

Thanks,

Mike
