How to: Safari running slow? Try using Google Public DNS

December 6, 2009

As everyone knows, Google is taking over the world one highly useful, well-implemented Web function at a time. The latest piece in this puzzle is the addition of public DNS services, which can be really helpful in making your Mac faster online.

When it comes to squeezing every drop of performance out of the Internet, in addition to cleaning out your caches and cookies on a regular basis, you can also configure your Mac to use a third-party Domain Name System (DNS) service, which can significantly (your mileage may vary) improve how fast you get from here to there.

Thereupon, last week Google announced their eponymous Public DNS service, which is an open, public and completely free service that might just be faster than the DNS service you’re using now. Benefits are said to include:

  • Performance“”Google Public DNS implements “smart” caching to increase the speed of responses.
  • Security“”DNS is vulnerable to various kinds of spoofing attacks that can “poison” a nameserver’s cache and route its users to malicious sites.
  • Correct results“”Google Public DNS does its best to return the right answer to every query every time, in accordance with the DNS standards.
  • How to do it

    1. Go to System Preferences -> Network -> click “Advanced”

    2. Click the “DNS” tab and then the ” + ”

    3. Paste or type in 8.8.8.8 and 8.8.4.4.

    4. You are now good to go, enjoy!

    That was easy but, as noted above, it’s only one of the things (cache n’ cookies above) you can easily do to make your Mac a little faster on line.
