The backend... is a busy place. Learn all about DNS and how your browser decides what to do when you type "community.spiceworks.com" into the URL bar (other than sing for joy). It doesn't actually just guess what the IP address is for the site. And no, your browser doesn't come from the "factory" knowing every website in the world. Get the lowdown on all things DNS as well as a brief history on phone operators!
