What is Google DNS

Benefits of using Google DNS – 8.8.8.8 and 8.8.4.4

  1. Ensures the DNS is being resolved correctly
    As you probably know, the default DNS on router is your ISP’s DNS. Often ISPs block access to certain resources be resolving their site names to a “wrong” IP-address. For instance if ISP wants to block access to example.com their DNS would resolve example.com to 127.0.0.1 or another fake IP. To avoid such blocking it would be enough to set 8.8.8.8 or 8.8.4.4 on router or PC and use them to resolve the correct domain names.
  2. Faster resolve speed
    Google DNS resolves hostnames faster that many DNS servers that belong to ISPs.
