The average Internet user probably knows next to nothing about the Domain Name System or DNS. It’s a system that is mostly behind the scenes, even though it is absolutely essential to how the Internet works. When you type in www.onedayonejob.com, your host checks its records (which are constantly updated) for an entry corresponding to the domain name. If it’s up to date and working properly, it will resolve the domain name to the Internet Protocol address 98.158.181.7 (every device connected to the Internet has an IP address). From there the request will get passed on to my name server, and you will be directed to the proper site (since www.onedayoneinternship.com is hosted on the same server). Not many people realize how important a good DNS server is. If your ISP doesn’t update their DNS list often, you may not be able to access a site that moves to a new server. You might also get redirected to an annoying page filled with ads when you type in an invalid domain name. Or you might be using a slow DNS server that takes forever to connect you to the right server. OpenDNS is a company that solves all of these problems and more. They are based in San Francisco, CA, and they are “the leading provider of free security and infrastructure services that make the Internet safer through integrated Web content filtering, anti-phishing and DNS.”
