Google has just introduced their Public DNS service as part of their ongoing effort to make the web faster.
Since Google's search engine already crawls the web on a daily basis and in the process resolves and caches DNS information, they wanted to leverage their technology to experiment with new ways of addressing some of the existing DNS challenges around performance and security.
Google Public DNS is offered freely to the general public to:
- Provide end users with an alternative to their current DNS service.
- Help reduce the load on ISPs' DNS servers by taking advantage of their global data-center and caching infrastructure.
- Help make the web faster and more secure.
- Performance: In addition to load-balancing user traffic to ensure shared caching, Google Public DNS implements "smart" caching to increase the speed of responses.Click here for more technical detail on how Google Public DNS can improve web browsing performance.
- Security: DNS is vulnerable to various kinds of spoofing attacks that can "poison" a nameserver's cache and route its users to malicious sites. Google has implemented several security measures in their DNS servers. Click here for more technical detail on how Google Public DNS is protected from security threats and mitigations.
- Correct results: Google Public DNS never blocks, filters, or redirects users, unlike some open resolvers and ISPs.
