The DNS translates the name into its numeric equivalent.

A few words from Tech Support:
"When you call us to have your computer moved, be sure to leave it buried under half a ton of postcards, baby pictures, stuffed animals, dried flowers, bowling trophies and Popsicle art. We don't have a life, and we find it deeply moving to catch a fleeting glimpse of yours."
