Google now offering a DNS service

ethernet

The choice broadens. Glad to see another choice, even if it's "OMG-Google-knows-everything-you-do". Using OpenDNS and happy with it so not in any rush to try this.

Announcement: http://googleblog.blogspot.com/2009/12/introducing-google-public-dns.html

More info: http://code.google.com/speed/public-dns/

Servers: 8.8.8.8 and 8.8.4.4

How do the google dns antimalware features compare to those offered by open dns?

Jonathan

The servers are surprisingly fast. I tested them earlier against my isp's DNS servers and there was no more than 5ms in the difference, and in some cases, they were actually faster than my isp's.

And Google can track every site you go to even when you don't use their spying crappy search engine.

You can block these with noscript.

Noticed this from a few pings as well.

From http://arstechnica.com/security/news/2009/12/google-public-dns-service-not-ideal-for-everyone.ars:

The routing system simply delivers packets addressed to either address to the closest Google Public DNS location. So users in different places around the world will be talking to different instances of these addresses, making for faster round-trip times, which is important for good DNS performance. This mechanism is called anycast.

I've changed my DNS to googles, but what are the advantages?

There's no advantage unless your ISP has dodgy DNS servers.

Looks like they have servers in Dublin:

Curious that these Google DNS servers aren't using Google IP's....

Google DNS servers vs BT Ireland DNS servers.

I'm not very good at reading that log, but would you be able to explain in simple terms which one is better, as I am also with BT Ireland.

The areas I highlighted are the bits to look at.

dig @8.8.8.8 --> Google
dig @89.19.64.164 --> BT Ireland
The response for each command is highlighted below it.


The difference is negligible really. 4 msec difference at most.

I'd stay with BT.

I wonder who owns them? :P

Level3 own the whole 8.0.0.0 block.

I've tested around 1,000 queries now, over my Digiweb connection at peak and off-peak.

By test, I mean a query, rather than just pinging.

For popular domains that should be cached (and I requested them before my tests, to make sure they wer), the average fastest was Google, then OpenDNS, and last my ISP Digiweb. For uncached, OpenDNS, Digiweb and then Google. Given that the vast majority of requests for the vast majority of users will be cached, Google seems to have the upper hand. For uncached queries, there were a number of large (multi-100ms) spikes which skewed the results. If they sort those out, then they'll be a DNS service to contend with. They've stated what they'll do with the data, so now it's up to you as to whether you believe them or not.

They are more memorable though. Win!
