I use Public DNS Servers on any connection I set up. They are always hands down better in performance, reliability, and actually following RFCs. Not to mention, they're typically more up to date to processing specific types of records. Some of them such as OpenDNS also provide some nifty features.
Not better performance here.
Can't remember the last time I had an ISP DNS reliability issue.
Which RFCs is Frontier DNS not following that Google, OpenDNS, or Level3 DNS are?
Which specific types of records are Google, OpenDNS, or Level3 DNS processing that Frontier is not?
OpenDNS also does redirection (DNS helper). Correct? Do they have redirection opt-out (without an account)?
Unless there is some specific must have need, I opt for the typically faster ISP (Frontier) DNS servers. Though since queries are locally cached, a few milliseconds speed diff is not typically much of an impact.
Being closer to the customer, ISPs if they chose to take advantage of it have a performance advantage over 3rd party DNS providers. For as long as I've been with Verizon/Frontier FiOS their DNS servers have always been the fastest for me. And I've never had any significant reliability problem. And they seem to be resolving all the record types I need. As for nifty features, well that's not DNS's role, and they are probably not RFC/standards.
So unless there is some specific capability I must have, there is no reason to use 3rd party DNS servers. I do use the non-helper servers though. And if they didn't provide those I'd almost certainly use a 3rd party that didn't do redirection.
In my opinion people make a DNS mountain out of a mole hill when it comes to ISP vs. 3rd party. I get tired of blanket statements that 3rd party DNS is always better than ISP, it's just not the case, and recommending people switch without a specific reason/need. 3rd party DNS is not the best for everyone in all cases.
My recommendation for Verizion/Frontier customers is to use ISPs DNS unless there is a specific reason 3rd party DNS is needed.
