Apparently you can make money buying domain names. You look for expired ones that were registered at one time but the owner did not re-register. Often that happens because the owner didn't get to it in time. It has to be re-registered very quickly or it goes back on the market and anyone can buy it. Domain names can be registered from one year to ten years. Each day thousands of expired domain names are put on sale and some of them came from well established domains. You can make money buying domain names that have expired by purchasing them for between $5.00 to $50.00 and then selling them for $150.00 to $1000.00. Sometimes it's the original owners buying them back. A drop registrar is what they call a place where they offer for sale the expiring domains. Domain name auctions are the place to go if you want to buy the names straight from the owner. Some of these names can fetch a pretty high price. If you are looking for a domain name and who owns it try using the domain name search engine.
