There can only be one of each domain name, so you'd best register your domain name before someone else does. This could save your business money and time in the future. Even if you have no intention of developing a website right now,we strongly recommended that you register your domain name now, because there are no guarantees that it will still be available in a year, a month, a week , or even tomorrow.
Having your own domain name means that you need never change your email or web address and once registered the domain name belongs to you.
The domain is yours for as long as you so wish, no one can take the domain from you and should another company want your domain name it is up to you whether you sell it or not (and how much for!).
