OpenDNS is a free service worth checking out. It may help to speed up your Internet experience, make it safer, and handle common typos in website addresses you type into the address bar. First, let’s take a look at what a DNS (Domain name server) does.
When you type a domain name (like www.e-volutiononline.com) into your browser the browser will pass this request onto the network system on your computer. From there it is passed on to the Domain Name Server your networking system has recorded as being the DNS it must use. This DNS (two of them actually) is typically provided by your ISP (the company that gives you access to the Internet. From here if the DNS goes not have a record of the domain name you have requested it will ask another DNS server for this info. Every active domain name has an IP (Internet Protocol) address associated with it. This is the a unique code that differentiates one node/computer from another. The code is in the format 000.000.000.000. The IP for the domain Microsoft.com is 207.46.230.219.
Your computer is then routed to the server to which this IP address is allocated. The browser then starts downloading the HTML content (or whatever content is there) and turning it into a web page you can view or a file you can download, etc.
So, what OpenDNS does is provide the service your ISP normally provides, with the claim that their service is superior. You can learn more about it at www.opendns.com
To use their service all you have to do is access the web control panel of your router (assuming you use ADSL) and edit one setting. The OpenDNS site gives instructions on how to do this. It takes about two minutes.
