DNS Test - BB-Hosts

Hi All!

I am trying to perform DNS record lookups via the bb-hosts dns directive.
My directive is as follows:

0.0.0.0 dnsserver.domain.com    # dns=a:www.google.com

if have also tried

0.0.0.0 dnsserver.domain.com    # dns=www.google.com

The result does not show the record lookups but only shows that the DNS
service is OK (up)

Can anybody shed some light as to why this is not performing the nslookups?

THANKS!
