Lately I've noticed a lot of questions in Q&A centering on purchasing expired domains. A lot of our members have expressed interest in buying old domains for a variety of prices (some are cheap, some are going for upwards of $50k) and want some advice on what to do with the domains once they've been purchased. I'm no domainer, nor am I an expert in such a business tactic, but I generally recommend one of three different options for an expired domain (and would love to hear more if you've got any).
Today, the story is different. Domain name registrars realized that they could auction expired domain names to the highest bidder and generate additional revenue. If no one wanted the domain names in an auction, the domains would then drop and become available for anyone to register. Much of the time, however, domain names are successfully auctioned.
