Sedo.com is a special marketplace for domain names and claims to have over 24 million domains in its portfolio. Already registered domains that were once used for business or private purposes can be searched for and purchased here by subject area. Since many good domain names are already taken, it is worth taking a look at this marketplace. Domains can be purchased directly or auctioned here by interested parties. There are no fees or commission for the buyer. Sedo GmbH* (*limited) in Cologne is part of United Internet AG and claims to be the largest marketplace in the world in this regard. 700,000 domains are said to have already changed hands via this marketplace.
