Domain backorder is a service made available by ICANN-authorized providers and it is the best way to acquire a good domain name that was owned by some third party and was left to expire. When the registration period of a domain has expired, the aforementioned becomes inactive, but is not deleted immediately. Instead, the owner has a few months to renew it. If this does not happen, the domain enters a deletion period that lasts about 5 days and then it is deleted, so everyone can register it. The backorder service enables you to make an order for such a domain name with a registrar company and they'll attempt to register it automatically once it is available. That way, you will be able to get an easy to remember and attractive domain for your Internet site and although such domains are registered on a first -come, first-serve basis and there isn't any warranty that you'll acquire the desired domain name, using an automated system will give you a lot better chance than if you keep checking whether the domain is erased and try to obtain it personally.
