The Most Expensive Domain Names in Internet HistoryA look at URLs that have sold for $1 million or more.

It is estimated thatmore than 500 URLshave been bought and sold for $1 million or more.

We scoured domain name resourceDN Journaland put together a list of documented million-dollar, domain-only sales. Some have been squatted on for 20 years and have only recently traded hands.

Not surprisingly, sex- and gambling-related domains are some of the biggest money makers.

Below, check out the most expensive domain names of all time.

Note: Web businesses have other assets and are not domain-only sales, so they were not eligible for this list. For example, Insure.com was bought for $16 million as a fully-operating, profitable company. DN Journal reports only the domain names sold after 2003 because prior sales are not verified by credible sources.
