Google Launches Public DNS Resolver 540
AdmiralXyz writes "Google has announced the launch of their free DNS resolution service, called Google Public DNS. According to their blog post, Google Public DNS uses continuous record prefetching to avoid cache misses — hopefully making the service faster — and implements a variety of techniques to block spoofing attempts. They also say that (unlike an increasing number of ISPs), Google Public DNS behaves exactly according to the DNS standard, and will not redirect you to advertising in the event of a failed lookup. Very cool, but of course there are questions about Google's true motivations behind knowing every site you visit."
It's their logical next step (Score:1, Funny)
They were limited to knowing only about the sites you searched for, can't have that, bad for business. Now they can track all of the sites you visit. Since Google is our warm fuzzy giant corporation that we can trust, there is no problem.

Wow the people at OpenDNS [opendns.com] are going to be pissed by this.
Still 8.8.8.8 is a bit more memorable than 208.67.222.222

Would be interesting to know how much Google paid for those two 256 ranges to Level 3. One would think simple ip's like 8.8.8.8 would cost some nice amount too.
Or maybe they should had used the coolest ip on the net, aka
> host 69.69.69.69
69.69.69.69.in-addr.arpa domain name pointer the-coolest-ip-on-the-net.com.

Of course you can still have cache misses.
You: Gimme goat.se
Google: That's not in my cache, hold on.
Google: Hey auth DNS gimme goat.se
Auth: K, here.
Google: Hey you, here.
You: K.
Your mom: Gimme goat.se:
Google: Yeah, I have that, here.
Your mom: K.
Your dad: I NEED the goat.se !
Google: Yeah I have that, but I need to recache it. Here's what I already have, it's probably still good.
Google: Hey auth DNS gimme goat.se
Auth: K, here.
Your dad: WTF? Where's the gaping anus?!
Google: Yeah, looks like the one I gave you before was wrong. No worries, this one is fresh.
Your dad: Sweet mother of corn holes.
Updating your cache early doesn't solve anything. You get less of a chance of misses only because you've checked more frequently. This comes at a performance cost on Google's end. Any DNS provider can cache anything for however long they want and return whatever result they think is valid.
The obvious thing to do is return your most recent authoritative result for cached domains or get one if it's not a cached domain. Choosing to empty out your cache after something has expired vs. refreshing it from auth is a performance decision. As is choosing whether or not to dump something when updating, or keep it around in case you get requests for it while you're updating. As is the overall frequency with which you update your cache.
No magic, brilliance, or good will on Google's part here - just horsepower and the willingness to operate at a financial loss in order to mine more data.

4.2.2.2 and their ilk are free and non-redirecting. You can use 4.2.2.1 4.2.2.2 4.2.2.3 4.2.2.4 4.2.2.5 or 4.2.2.6
They are run by L-3 and sitting on major backbones, and the ip addresses are pooled, so that you will likely get a server that is geographically near you when you use one of those addresses.
But with Google you don't have to use those complicated numbers any more. It's all much more simple. All you have to use is
dns.google.com
Much simpler to remember.
If it doesn't work, it's because it's still in beta. Just try again.
