Hence you can change your DNS settings as described at Google code (code.google.com) with more details at Google code blog (googlecode.blogspot.com).

Apparently for those that own/manage websites/blogs there is talk that a site's loading times (searchengineland.com) may be used in ranking web sites listings in search results next year; Perhaps the need for Google to offer their own DNS...

836408 2009-12-04 07:49:00 I'm using it now, its seems slightly faster but I havn't done any side to side test against open DNS. xyz823 (13649)
836409 2009-12-04 21:17:00 Very cool :D Chilling_Silence (9)

I appreciate the story, but geez the grammar is rubbish in that article.

I thought that Telstraclear users shouldn't use opendns etc. since Telstraclear caches their stuff differently.

You can't blame me for the story but I thought it may help.

I'm with Xtra and using OpenDNS. I wasn't planning to try GoogleDNS just yet anyway.

Same with Telecom, it can completely miss a fair bit of their caching apparently.

Agreed, the article could have been a little more in-depth, no mention of the connection type, no mention of the number of iterations tested, no mention of the time of day tested at, as all can have very different effects on the response times, especially when we're talking about the average difference being 50ms between Telstraclear & Google.

Of course, there's a high chance your own ISPs DNS servers will be fastest (Considering Telstraclear now own Paradise and the old Paradise DNS servers are hardly used, there's the possibility that for that reason they're faster than Telstraclears own main DNS servers), and that's shown for him using his TelstraClear connection.

Just running 3 tests on a Telecom ADSL2+ connection at 8AM in the morning I managed to find the top #1 spot varied between Paradise, Google & Telecom's nameservers. Interesting, next time I thought I should run something a little more complete and include all the international nameservers that DNS Benchmark uses ;)

Naturally, I'm posting my results, and I'd encourage any others to do-so too! Grab DNS Benchmark: www.grc.com

At approx 8:45AM on a Sunday, Telecom (Big Time) ADSL2+ connection with DNS QoS'd to above everything else on my line (My connection basically unused anyway - I made sure there was no other DNS requests during the benchmark), I ran 3 iterations with the standard DNS Benchmark nameservers + the following added:
8. 8. 8. 8 (Google #1)
8. 8. 4.4 (Google #2)
202.27.15 8. 40 (Telecom #1)
202.27.156.72 (Telecom #2)
203.96.152.4 (Rachel - Paradise)
203.96.152.12 (Kirsty - Paradise)
203.97.7 8. 43 (Telstraclear #1)
203.97.7 8. 44 (Telstraclear #2)

Test #1 Summary: My ISP (Telecom) came in 5th in the results. Whilst Google's are nowhere to be found (They're right at the bottom in-fact, search the text results for " 8. 8. 8. 8"), Level 3 Communications (Same name as Googles come up as) have come in at #11. Verizon cleaning up the Top 10, with 3 of theirs at the top of the list!


Test #2 complete results in text form: pastie.org

Test #2 Summary: iiNet placed first this time. TelstraClear came in 10th with their other DNS Server a little further down in the JPG list, and one of Paradise' also. Verizon again with 2 in the Top 10, no sign of Telecom this time though, they're half way down the list. Google again right at the bottom.


Test #3 complete results in text form: pastie.org
Attached file: Chill-DNS_Benchmark_3.JPG (www.imagef1.net.nz) (99 KB)
Test #3 Summary: TelstraClear all right at the top, one of Paradise up there also, and a few of Verizons too, though SpeakEasy won this time.


Overall summary: Google's thus far have been consistently slowest, right at the bottom when looking at the cached results.
The time between the fastest and slowest is <25ms for uncached lookup average.
However, if you notice in the last results SpeakEasy won at the top, look at the time taken for a .com lookup and compare that with Telstraclear, Telecom or Google. All are faster.
What does this mean for an end user? You're potentially not going to notice any difference in the resolution speeds when using any of these, they're all approx 190 -> 260ms. The difference between the min, max & average for all of them is so close, I'd suggest that it's not even really worth bothering changing from your ISP's DNS servers unless they're having issues, or slow down under load, which is potentially a good reason to use something such as OpenDNS or Googles (They don't just have two servers, but a whole farm of them).
There are, however, other factors which you may appreciate, such as OpenDNS domain filtering. Interestingly enough even though TelstraClear / Telecom have scored better in the Benchmark, in real-world "feel" tests, I'm certain I'm not alone in saying that Google / OpenDNS "feel" like they're resolving everything and the pages completing loading faster?


Please, post back your results, and also add in your ISP's nameservers if you know them, when doing the test.

Seems that resistance is indeed futile.....
