Set Up OpenDNS in Windows 7 (Faster Website Loading)

Do you have DNS issues? Are websites loading slowly? Is your ISP DNS Server slow? Is your browser not working at all? Answered any of the questions with yes? If so, you might want to set up OpenDNS on Windows 7. It’s really a simple configuration but can help tremendously.

Set UP OpenDNS

OpenDNS is a free DNS server that will do all the DNS lookups for you. If your ISP (Internet Service Provider, e.g. AT & T) has a slow DNS server, your DNS lookups will be slow. This in return will result in slow website loading. That’s why OpenDNS might help you to speed up your internet connection.

DNS: General Infos

But what is DNS and what are DNS lookups? DNS stands for Domain Name System. All domains (web addresses) are linked to IP numbers of so called nameservers that translate the domain name request to an IP. Simply put, DNS is like the telephone book of the internet. Your ISP DNS server is basically a large telephone book with many domains and their IP’s, but if that server is slow finding the correct number (IP) will take a bit longer.

OpenDNS has servers all over the world to optimize DNS queries and make DNS lookups blazing fast.. It’s a free service that you can rely on. It’s also helps to prevent phishing and has many advantages in general.
