Google’s Public DNS
In another step to control the entire internet, Google has launched public DNS servers for everyone’s use. DNS servers are used to lookup on what IP a particular domain or subdomain is located. For instance, ATBNet.us has the IP of 76.10.210.37. So, the DNS server will lookup ATBNet.us and find the correct IP and then your internet connection will connect to that IP and presto – you’re at this site.
Why would you want to use Google’s DNS servers? Well, for one they are very robust. Instead of having just one or two servers handle the DNS service, Google uses anycast which means many servers can handle this task. This also means a DNS server can be fairly local to you instead of jumping halfway across the world. Another reason why is that many ISPs setup redirection on their DNS servers which will take you to a generic search site if you mistype a URL. This search sites are just ways for ISPs to earn extra revenue and can often confuse users rather than help them find the right URL. Other than that, there are no major reasons to switch to Google’s DNS service. They don’t offer any way to block known malware and virus sites like OpenDNS as they do not wish to be in that business to block off parts of the internet even for good reasons.
So, if you are willing check out the Google DNS servers: 8.8.8.8 and 8.8.4.4. They are pretty easy to remember.
