I was afraid that's what it meant and that explains some of the odd 
results I've been seeing when changing my dns settings. It also means 
that I am not getting the services I paid Opendns for which raises a 
question of ethics. Should Opendns have known that a particular ISP 
operates this way? Wildblue/Viasat is a major ISP!

Wildblue shut down their mail servers several years ago and routed 
e-mail through Google, we are actually on gmail.com servers for e-mail 
and I wonder if the dns service did not become what it is at that time?

I will inquire of Opendns about this. Perhaps they can offer a solution 
... I am pretty well tied to my ISP since it is the only reasonably fast 
service available here in this rural area, we don't even have cable TV. 
There is dial-up but no DSL.

At dnsleaktest.com they describe a packaged solution for Windows VPN:

    3 basic steps to fix the problem;

     1. Before connecting to the VPN, set static IP address properties
        if you are using DHCP
     2. After connecting, remove DNS settings for the primary interface
     3. After disconnecting, switch back to DHCP if neccessary or
        reapply original static DNS servers

Which leaves wondering if there's a Linux solution available for my 
non-VPN system?

Thanks,

Bob
