Um, actually they're used to speed things up when an ISP has slower servers (which happens often). Also, some, like Norton are specialized to deal with malware, and can be used as an invisible (until something is blocked) layer of security.
Norton DNS is currently on my router. I saw it had better reviews than Comodo and I like to get different security from different companies.
Does Comodo DNS block malware sites that Comodo has sold certificates to? I asked this question before but no answers- anyone know now?
And I'd imagine that to be that the Comodo folks/fans went to work shunning anything that showed anything Comodo in a negative light I've been very happy with Norton since I started using it. I can't think of a single instance, thus far, in which is was wrong to block something.
Since removing ClearCloud, Norton DNS has been great for me. I alternate, every now and then switching to Comodo Secure DNS for a few days... But really, I only do it because it's so much fun to come back to Norton.
This is a utility to check DNS speed, courtesy of GRC, and guest for posting it: http://www.grc.com/dns/benchmark.htm From my location, Norton is fairly fast, but not the fastest, for security I rely on Sandboxie and Chrome.
Shouldn't DNS prefetching essentially mean that all DNS servers will essentially give the same real-world performance?
Yes, for the first request. If I'm on a wilders page and someone has linked to facebook Chrome will prefetch the facebook DNS before I click the link. That's how I understood it. I also don't know if it's cleared, but if it works the way I think it does it makes no difference.
DNSSEC http://www.dnssec.net/ the most secure but not free a good secure free one is comodo dns works fine 4 me fast to benchmark dns checker may get you a fast one but the fastest is not always secure ,who do u trust to view what website u go to? is its cache safe? does it have a A+ rating
You've misunderstood me. Not for the first request, as in, a DNS lookup obviously has to be made for it. It will also be made for the facebook page. Nearly every third party DNS provider supports DNSSEC, including Norton.
Yes, of course the DNS lookup has to be made at some point. But it's made before you click the link, therefor the load time is put at a point where you're doing other things.
If you're talking about the "guess what you click" feature of Chrome, I rarely see it being useful. Most people will type an address, click a bookmark, or perform a search then click on the first link within seconds. When reading most sites, links generally take you to parts of the site itself, it's not common to find links to completely different sites, excluding forums obviously. So you can't really justify removing the speed of a lookup as a competitive view between DNS service choice.
It's not a "Guess what you click" gimmick or anything. If there are 10 different domains on a Wilders page Chrome will perform the DNS lookups for each one. I believe all major web browsers do this. I'm not saying speed is the only thing to look for between two DNS services, in fact I'm saying that if you have a modern browser it makes absolutely no difference. One lookup could be .1ms and another could be 3 seconds. Either way you're going to have the resolution done before you even click the link.
