Even though you may have a high speed broadband connection, you’d still want to squeeze out some extra juice from it, especially when browsing websites. Switching to a public DNS instead of your ISPs DNS can be extremely useful in achieving this target.
As the Google Public DNS website explains some reasons to switch:
- Provide end users with an alternative to their current DNS service. Google Public DNS takes some new approaches that we believe offer more valid results, increased security, and, in most cases, better performance.
- Help reduce the load on ISPs’ DNS servers. By taking advantage of our global data-center and caching infrastructure, we can directly serve large numbers of user requests without having to query other DNS resolvers.
- Help make the web faster and more secure. We are launching this service to test some new ways to approach DNS-related challenges. We hope to share what we learn with developers of DNS resolvers and the broader web community and get their feedback.
Besides Google DNS, you have several different options including Norton and OpenDNS. You could choose to manually go about checking which of these gives you the best results. Or, a more efficient way to go about it is to use a software that does this job.
Public DNS Server Tool is a small utility for changing the DNS servers in Windows XP, Vista and 7 on the fly.
The software supports the following public DNS servers:
- Google Public DNS
- OpenDNS Family Shield
- Norton DNS
- Comodo Secure DNS
- Scrub DNS
- DNS Advantage
Simply download and run the software, pick an option of which server set to use and you’re all ready. Switch between the various options to figure out which gives you the best performance. You could also use namebench which is a utility that allows you run some checks that will benchmark the various servers.
