Hobbit server resolving client name in correctly

I have a new installation of Hobbit 4.2.0 monitoring a private network
(192.158.151.0/24)  It is currently monitoring a number of Windows servers
with BB clients reporting data to hobbit.  The Hobbit system is configured
to use two Windows DC's for DNS resolution.  Hobbit however is reporting in
the CONN column that one of the DC's has a public IP address on the
64.20.33.0/29 network.  How is this happening?  The BBHOST file has the
correct local IP address and FQDN host name.  None of the client specific
data is registering with Hobbit either.
 
If I perform a lookup from the system, the host name resolves correctly to
the private IP address of this box.
