Domain backorder is a service offered by ICANN-certified service providers and it is the easiest way to acquire a good domain which was owned by some third party and was left to expire. When the registration period of a site is over, the latter becomes inactive, however it is not removed instantly. Instead, its owner has a couple of months to renew it. Provided this does not happen, the domain enters a deletion period which continues about 5 days and following that it gets deleted, so everyone can register it. The backorder service allows you to place an order for such a domain with a registrar company and they will try to register it instantly the moment it is on the market. That way, you can get a short and attractive domain name for your Internet site and although such domains are registered on a first -come, first-serve basis and there isn't any guarantee that you will acquire the desired domain name, using an automated system will provide you with a lot better chance than if you keep checking whether the domain is deleted and try to obtain it manually.
