For websites with a lot of external links to Facebook and other sites it could actually be an improvement in the short term. Long term though, once you have the addresses resolved there is no overall improvement to the speed of the connection. Effectively people are misreading a long time to resolve a name as being the same as its "ping". Of course, the purpose of Google DNS isn't to be faster.

I think small sites may indicate that the results can be cached for a long time, but the big sites now don't want to risk being offline if a site is unavailable and DNS is one way of helping with that — Matthew Steeples.

MatthewSteeples one millisecond long request every five minutes still won't produce any noticeable lag in online games. Unless your game protocol is seriously wrong then you won't be using any DNS once you're connected as the connections are persistent.

I was just pointing out that the first paragraph is entirely wrong. Dylan Rozendom Dylan Rozendom 6 6 silver badges 16 16 bronze badges. So should I stick to opendns or use the default one? Lynob That is really up to you. I use google myself.

But my understanding is that you are having issues explaining to someone about using 3rd party DNS on the WAN configuration of the router right? Assuming you're running a Windows DNS server for a domain setting I think we would need more detail In the AD world, Best practices for configuring a new Active Directory.

In the absence of an AD server perhaps you may get away with that, but in an AD environment it is best practice. Google DNS is fastest for me on Comcast. For AD server's B themselves, there has been some debate over the years, including inconsistencies in Microsoft's own documentation. Do this for every AD server.

If the box is a domain controller, then Otherwise, multiple domain controllers have to point to each other as primary DNS. The primary has to completely fail a DNS request altogether i.
