Google public DNS server

 has launched its own Dns server to improve our web experience.
This new service allows u to use google specified DNS(domain name servers) severs to speed up our intenet access by resolving names faster.As we have already talked about dns servers.DNS servers' duty is to domain names with unique IP addresses.

 we know that whenever u type a domain name in ur URL bar or address bar the requested page gets displayed .but computers can understand only numbers hence they assign each domain with a unique address called IP address.u may get a doubt that "computers cannot understand english  then how can it display correct webpage in my browser when i type da domain .This mapping of domain name to IP address is done by DNS servers.IP addresses are like telophonenumbers mapped to our names.  add

Actually all this conversion happens automatically .The DNS server present in our system settings is actually provided by our ISP  providers.These servers are slower when compared with powerful google servers.

By changing ur DNS server settings to google DNS server settings u will enjoy 3  benefits

1)Speed-due to frequent refreshment of caching

2)Security-due to Google Public DNS makes it more difficult for attackers to spoof valid responses by randomizing the case of query names and including additional data in its DNS messages
.
3)Validity: Google Public DNS complies with the DNS standards and gives the user the exact response his or her computer expects without performing any blocking, filtering, or redirection that may hamper a user's browsing experience.
