Fix Slow Browsing — and More — With OpenDNS

"For most small businesses, a reliable connection to the Internet is vital for both communication and commerce. A key component of Internet access is the Domain Name System (DNS), which allows you to reach sites using familiar and user-friendly names like smallbusinesscomputing.com rather than inscrutable and difficult to remember IP addresses like 63.236.73.55. Whenever you access a Web site, send or receive e-mail, chat via instant messaging, or use any other type of Internet application, DNS is working behind the scenes matching domain names to IP addresses.

"As you read this, your business is probably relying on ISP-provided DNS servers to reach sites and services on the Internet. They often do an adequate job, but they’re prone to sluggishness (and sometimes outages). Switching your business over to the independent DNS service provider OpenDNS, on the other hand, can make Internet access a bit speedier and safer for everyone on your network, as well as provide added features like content filtering so you can determine which Web sites your employees can and can’t visit.

"OpenDNS uses a combination of caching technology and a network of strategically located servers that generally perform DNS lookups much quicker than ISP servers do. Considering that loading all the components of a single Web page can often involve lots of individual DNS lookups, saving even a fraction of a second on each can really add up. OpenDNS also provides a phishing filter and checks every site you visit to make sure it’s legitimate before taking you to it."
