Verizon DSL does not permit OpenDNS as primary DNS ??

I have Verizon DSL at home in Manhattan, NYC. It's been pretty good the last year or so.

 

Here's the issue: I set my wi-fi router (Actiontec GT784WN-VZ-1.1.6) to use OpenDNS as its primary DNS source. (208.67.222.222 and 208.67.220.220). And, yes the router shows the two OpenDNS URLs as DNS Addresses #1 and #2 in its Gateway Parameter page. And the test page at OpenDNS indicates it is working.

 

However, if I run a Verizon HSI Field Ping Test (which gathers info from the Verizon CO and my DSL circuit), it says:

 

[08/25/13 16:11:40] PPP Peer IPv4 Address is [my IP - deleted here]
[08/25/13 16:11:40] PPP Peer IPv4 Address Mask is none
[08/25/13 16:11:40] PPP Peer IPv4 Primary DNS is 68.237.161.12
[08/25/13 16:11:40] PPP Peer IPv4 Secondary DNS is -
[08/25/13 16:11:40] PPP Peer IPv4 Primary WINS is -
[08/25/13 16:11:40] PPP Peer IPv4 Secondary WINS is 71.243.0.12

 

Well, those last two are NOT OpenDNS. So, what's the story? What are the URL-IPs above in the Vz HSI Field Ping Test as "Primary DNS" and "Secondary WINS"? Is there a way to make them the OpenDNS URLs instead? Thanks.

  As long as the command "nslookup -type=txt which.opendns.com." indicates that you're using OpenDNS, you don't have to worry. Who knows how they obtain these measuring results...

  Although their DNS server addresses are shown in the results, they may not be in effect at all.

  Mr. Rotblitz - I get the following Non-authoritative answer: which.opendns.com text = "1.nyc" Well, that looks good, even if it is "Non-authoritative". Are you confident that Verizon's choice of Primary DNS in its external CO circuit does NOT override my choice of OpenDNS in my router? Thanks.

  As long as that nslookup command comes back with the OpenDNS location (New York City in your case), and as long as http://welcome.opendns.com/ indicates that you're using OpenDNS, you can be confident that your ISP's DNS service is not in effect.

  "even if it is "Non-authoritative"."

  All OpenDNS responses are non-authoritative, because OpenDNS is a recursive DNS service, same as your ISP's, not an (authoritative) DNS hosting service. If you ever get an authoritative response from OpenDNS, something is incredibly wrong...

  Yes, http://welcome.opendns.com/ shows that I'm using OpenDNS.  All seems good.  Please just keep an eye out to make sure Verizon and the others don't suddenly interfere in future.  Thanks.

  I'm a user like you and don't have a way to "keep an eye out" on Verizon...
