Admin As you are probably already know, dot com, dot net, and dot org domain names (and some other domain known types) are generally sold on a first come, first served basis – that is to say that the first person to identify a previously unregistered domain name, can simply go a domain registrar, pay the registration fee, and get that domain for themselves. The domain is then no longer available for anybody else, unless the original owner chooses to sell it or transfer the domain to somebody else, or the domain owner stops paying the annual renewal fees. In the case of non-payment of renewal fees, the domain goes through a gradual multi-step expiration process, before becoming available to the public to register again.
There are a few exceptions to the above general rules. For example, in cases where a person has registered a domain name that infringes a trademark holder’s rights (known as “cybersquatting”), the trademark holder may be able to get hold of the domain, but for the most part, the only way to obtain a previously register domain name is either to buy it from its current owner, or wait until the current owner fails to renew it, and then buy it once it becomes available to the public again.
