(Thanks, Mark!)

Update: Mark sez, "I believe that 466453.com exists for users who are accessing google via mobile phones that don't have T9 text entry."

Update 2: Tijl sez, "they own gngjd.com as well, but.. that doesn't link to the main page! It's what happens when you type an URL on most phones without going into numerical mode first. T9 is rarely enabled for entering an URL by default (though some phones do). Image the potential! Register gumds.com today, Apple laywers on your doorstep tommorow!"

Update 3:Andrew sez, "http://www.600673.com/ resolves to Google in h4x0r style."
