This is a common question that people ask to experts and on forums when the domain name they want is unavailable for registration. If you are also facing similar issue then there are various things you could do about it such as you can try some alternative extension, get patriotic by using .co.us or .net.us or just name.us etc, you can add a keyword in the name of your domain, approach the owner of that domain and make an offer to him for it or use domain backorder service.
You can say domain backorder is the cheapest option to buy a pre-registered domain. It is a service that helps you attempt to acquire a domain name when it becomes available for registration. But placing a backorder does not guarantee that you will acquire the domain name. The current registrant might renew the domain name on time or so.
Not all domain registrar provide you domain backordering service but there are some such as SANGKRIT.net. To backorder any domain, you simply need to search for the domain name here.
Yes it will show the domain is unavailable but what you need to do now is click ‘Learn more’ present right next to ‘Still want it?’ text where the domain unavailable message ends. Once you click that, it will show you option to backorder that specific domain name.
There are many variables that affect the Domain Backorders process. For instance, you might have to participate in an online auction to get your backordered domain, and the auction might be public or a private one. This process is in place to provide everyone an equal opportunity to acquire unavailable domain names.
