Make your Web surfing faster and reliable with Google DNS Servers

Slow address resolution is one of the major reasons for slower browsing. The address resolution is done by the DNS server. In simpler words, DNS Server converts the human readable web addresses (Like www.techskipper.com) to computer readable addresses (also know as IP address). When we write website address to internet explorer and press “Go”, the address is forwarded to DNS Server which translates this address to an IP address. If DNS Server takes time to resolve the address, our browsing is obviously slowed down.

Recently, Google has launched its public DNS servers to provide faster, secure and reliable web surfing to the end users. Google in its own words:

We are offering the service to the public in the hope of achieving the following aims:

  • 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 experimental 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.

Now you have three options: 1) Use Open DNS 2) Use ISP DNS 3) Use Google DNS. Most people stick to the DNS provided by their ISP but the web experience might not be that good. But here is a catch, the closer the DNS server is to the user, lesser is the time for request to reach the DNS server. One can say: my ISP DNS is closer to me than Google DNS. Well, Google is smarter and has addressed this by locating its servers worldwide as it says:

For closed resolvers, this is not really an issue. For open resolvers, the closer your servers are located to your users, the less latency they will see at the client end. In addition, having sufficient geographical coverage can indirectly improve end-to-end latency, as nameservers typically return results optimized for the DNS resolver’s location. That is, if a content provider hosts mirrored sites around the world, that provider’s nameservers will return the IP address in closest proximity to the DNS resolver.

Google Public DNS is hosted in data centers worldwide, and uses anycast routing to send users to the geographically closest data center.

Note, however, that because nameservers geolocate according to the resolver’s IP address rather than the user’s, Google Public DNS has the same limitations as other open DNS services: that is, the server to which a user is referred might be farther away than one to which a local DNS provider would have referred. This could cause a slower browsing experience for certain sites.

Now here is a procedure to change your DNS server to Google:

Step 1: Go to Control Panel>>Network and Sharing Center>>Change Adapter Settings.

Step 2: Right Click the connection to your ISP and select Networking tab.

Networking

Step 3: Choose “Internet Protocol Version 4 (TCP/IPv4)” and click properties.

Setting DNS

Select “Use the following DNS server addresses” and write 8.8.8.8 in preferred DNS server and 8.8.4.4 in Alternative DNS server. Click OK. You may require to reset the connection to apply the changes.
