If you are working on a new project where you need to domain name registration names there are different options that are available to you. You can either register a fresh new domain from a domain registration or hosting company or you can buy a domain name from someone else. If you are going to buy a domain name from someone else it might benefit you more if the domain is old, the keyword is relevant to the site you are building and if they have a page rank that would be a bonus. If you can find such a domain that would be perfect for your website because search engine optimization of your website would be easier since search engines trust old domains more, so you do not need to wait to establish your new domain if you were to register a new one. Having back links already can also help get your website indexed faster.
