your computer uses DNS like a database. DNS translates from a name like "eff.org" into a raw number called an IP address. All internet traffic requires these numbers to work. Some computers do your DNS directly, but with most personal computers, your PC asks another computer at your ISP or corporation to do the work. The important point is that the looking up of the name is normally done by a computer you or your site controls, or one you pay to do such work for you. |
