Dubdomain
An expired domain list is a domain name registered by an individual or business that has not been renewed prior to its expiration date. It can be re-registered by someone else after it expires.
You can find out when any domain name expires by using one of the many free search tools like Whois.
Tools like Whois tell a lot, including exactly when the domain registration period expires, who the current newly registered domain list is (if not hiding it), and their contact information.
If you want to check who owns a domain name, you can get help from websites like Whois or Tucows. All you have to do is search these websites for the full URL or the full domain name. If privacy is not an issue, you can find all available information about the registrant.
