Host/nslookup/dig queries wrong server

[Lightner, Jeff]

You might want to file a bug report with RedHat.

I just looked through the notifications I got last year from RedHat
regarding various bug and security updates to the bind packages and none
of them mention this change.

Can others on the list verify the default (non-RedHat) bind-utils
package's host command should NOT resolve if server is specified and the
specified server doesn't resolv?

Whats odd is FC8,9 and 11 are ok. 

10 uses 9.5.1
Centos uses 9.3.6

It appears therefore that Redhat are somehow causing the issue when
building
certain versions.

Thanks for your help proving what it is at least I can look at upgrading
or
downgrading to solve the issue.
