According to ComputerWorld’s Preston Gralla:
Here’s the simplest way to hack DNS to speed up your Web browsing: Use free, superfast DNS servers run by the OpenDNS service instead of your ISP’s DNS servers. OpenDNS has a monstrously big DNS cache, with DNS servers around the world, so you’ll be able to retrieve IP addresses from it more quickly than from your ISP’s DNS servers. The addresses of the OpenDNS servers are 18.104.22.168 for a primary DNS server and 22.214.171.124 for a secondary server.
OpenDNS protects millions of people a day across hundreds of thousands of schools, businesses and homes. We block phishing sites, give you the power to filter out adult sites and proxies among more than 40 categories, and provide the precision to block individual domains.
OpenDNS is the world’s largest, fastest-growing DNS service provider. Millions of people worldwide (and growing) trust us to handle their DNS and Web-content filtering needs. Why? Because we take a fresh approach to the Domain Name System and make it smarter and more powerful than it’s ever been.
OpenDNS was founded in late 2005 by DNS expert and entrepreneur David Ulevitch. With its team of the brightest and most creative minds in the industry, OpenDNS is constantly adding new features to improve the Internet experience for everyone from sysadmins at large organizations to parents at home.
