Public DNS Can Make Your Browser Go Faster

If your browser is too slow, you can use public DNS to speed up browsing. These servers are available all over the Internet.


Your ISP designates a DNS server to your computer. This can be slower than the public servers and may be restricting you from browsing some websites.

How to Change a DNS Server

The method will vary depending on what version of Windows is installed on your system. However, the result is going to be the same.

In Windows 7 and Vista

Click Start and go to Control Panel. Select Network and Internet. Right click Network and Sharing Center and select your connection. After double clicking Internet Protocol (TCP/IP), enter any of these DNS addresses:,, or

In Windows XP

Click the Start button and go to the Control Panel. Right click Network Connections and double click Internet Protocol (TCP/IP). Enter any of the server addresses given earlier. Start browsing.

Overview of DNS

The DNS (Domain Name System) is the technology used for Web name, Internet domain and site management. DNS allows you to type names like www.website.com and your computer will find it. The system also has many servers.

A server refers to a computer that is registered to the DNS. A server operates specific types of networking applications. It has Internet host addresses, a database and a public IP address. A DNS root server interacts with one another via private network protocols. Arranged hierarchically, the root servers are stationed at the top. These servers have the database of domain names and their matching Internet protocol addresses.

The Internet currently has 13 root servers. These are named A, B, C to M. One is in Stockholm, Sweden, one is in London, and one is in Japan and the rest in the US.

The Hierarchy

The 13 root servers have all the IP addresses and domain names. Every other server is configured at the hierarchy’s lower levels. These have only certain parts of the database. Servers at the lower levels are maintained by Internet Service Providers (ISPs) or businesses.

For instance, Google has many servers to manage their domain names. The same thing is true with your ISP; they have DNS servers to monitor their connections.


The set up is client/server. A web browser works as a DNS resolver / client. It sends out requests to your ISP’s provider. If servers get a request that is not in their database, it will become a client. The request is then relayed to a server that is higher up.

It will keep sending the request until it reaches a server that has the request your computer asked. When it is found, the data is sent back to your computer, again in a hierarchical manner.

Other Information

Your home network finds these servers via a Web connection. Your ISP will give you backup and primary DNS server IP addresses. The information can be found on the Windows Control Panel at the TCP/IP connection properties.

It is also at your home network router’s configuration. There are also utilities that allow you to look up these settings. Once you find it out, you can easily change the server.

Many people have reported that using public DNS to speed up browsing does work. In some cases the speed gain can be significant. But it will also depend on the website and your location.
