OpenDNS



Do you want a boost in your Internet speed? Do you want a safer way to surf the Internet? Read on...

Each ISP (ie. AT&T DSL, Comcast High Speed Internet) has its own set of DNS servers. The DNS server will contain a huge list domain names and their corresponding IP addresses. The IP address specifies the exact location of the website's server. A DNS server is like the yellow pages phone book which contains the names and addresses of local businesses. When you type in a URL (ie. google.com), that request is first handled by the DNS server. The DNS server will perform a look up for that domain name and send your browser the ip address. All of this happens in a fraction of a second.

Unfortunately, each ISP maintains their own DNS server for their users. Therefore, if it goes down or gets corrupted or is slow, the user will be directly affected. So thats where OpenDNS comes into play. OpenDNS is a central DNS server system that is reliable, fast, and safe. What exactly does that mean for the end user?
  • Reliable - its highly available and more stable than the ISP DNS servers.

  • Fast - You are more likely to receive a faster response from OpenDNS, therefore, you will get to the website you want to go faster.

  • Safe - They have a large database of bad or malicious sites. Therefore, they will help to filter those sites in order to protect you. For example, if you accidently made a typo in the URL (ie. gooogle.com) it will catch it and warn you before allowing you to enter that website. This is a good thing as there are many bad people out there who register mispelled domain names on purpose in order to attract many visitors or potential victims by bombarding them with ads or spyware.
For those of you who are using routers, the instructions are simple. Just login to your router and look for DNS settings. Instead of "Get Automatically from ISP", specify the Primary DNS and Secondary DNS with the following IP addresses:

Primary - 208.67.222.222
Secondary - 208.67.220.220



That's it, you're done. I told you it was easy. For more specific instructions, visit the OpenDNS website.

Bottom Line
OpenDNS is easy to use and will make your surfing faster and safer.
