This Apache licensed, open source, not-been-update since June 2010 ran successfully for me on Mavericks 10.9

The application does support IPv4 ... but does not support IPv6.

With 'namebench', I was able to find some reliable IPv4 DNS "Domain Name" servers to use which also did not do annoying "DNS Hijacking".

To my surprise, Time Warner DNS systems had timeouts where the servers *never* responded. (Does Time Warner know they slow internet traffic BW consumption by dropping a % of DNS responses ???)

I dropped Time Warner DNS, made some other DNS changes, and now my internet access is faster and more efficient on the same connection ... thanks to 'namebench'.

FWIW, I just downloaded and ran this app on a new MacBook Pro Retina running OS 10.9.1 and it worked perfectly!

May currently be broken on OS X 10.8.2: consistently hangs at one point and never recovers. A similar report from an unrelated user has been posted on the Namebench forums with no response for 3 months.

Looks like this is a goner :(

Works fine for me in OS X 10.8.5


Me too… works fine with OS X 10.8.5 on a MBP. But yeah, development is nil. Too bad.

The app does not run period. It immediately unexpectedly quits the moment I open the program. I am running OS X (10.7.2) on a iMac 12,2 3.4 GHz Intel Core i7 with 16 GB of RAM, a 251 GB APPLE SSD TS256C and a 2 TB HD and a AMD Radeon HD 6970M graphics card with 2 GB of VRAM. If you need any additional info or need me to test something please respond.

This would be a great concept except for one thing. Seriously, you should remove the censorship check feature. Doing DNS queries for these web sites is a good way to get your door busted in during the middle of the night. At least include a warning or something so that people know what they will be connecting to. I was appalled at the list of sites that showed up on the results html page. Seriously?

Namebench is now at version 1.3. It fixes a critical bug that prevented the use of Alexa data under OS X.

MU doesn't mention that v1.2 is currently beta (1.2-BETA1).

The listing has now been updated so that it links to the real 1.2 release.

It uses EITHER your IE history or, better yet because I always delete mine, Alexa's 10000 list of top global domains from around the world. THEN you may select the data as weighted (statistically), randomized, or chunked. It will also advise of dns hijacks and the like avoiding them automatically in it's final report which is optimized for your region.
Nothing whatsoever to do with a google datamine nonsense review previously posted. I switched to treehoo anywho.

Using namebench 1.1 on a Macbook Pro running OS X 10.6.2 and an Apple Airport.

After I start namebench there is an inordinately long time searching.
During that time I lose DNS capability in that I get msgs that the page cannot be found.

When I quit namebench, this loss continues.

To restore my ability to use the internet, I must shut down the Airport and restart it.
