Thanks for the response. Here is the requested info. In the resolv.conf, I have masked some of the IP addresses, because they are on my organization's net. I find that surprising, actually. I didn't directly configure this .. it was done by the OS installation. And I've always believed that between the NAT and the host-only adapters, my vm was effectively isolated from any direct knowledge of the environment outside of the host OS. Maybe there's stuff about NAT I don't fully understand.

Code:
[root@vblnxsrv02 ~]# cat /etc/resolv.conf

nameserver 192.168.56.2

By way of contrast, I ran the same on a OL 5.6 vm, also with no configuration beyond what is done by the installation procedure. I find the difference in the resolv.conf to be be interesting.
