According to its WHOIS record, SDTBSM.COM was created on May 20, 2018 and expires on May 20, 2019. That makes the domain about 8 years old. It is registered through Shanghai Meicheng Technology Information Co. Ltd (IANA ID 1621) and is past its expiry date. The registrant is listed in China. DNS is served by v1.juming.com and v2.juming.com. Registrars are the companies accredited to sell and manage domain names, and the sponsoring registrar is the one currently responsible for this name. Registry locks add an extra layer of protection for valuable names, because changes then need manual confirmation by the registry. When a domain uses its own nameservers, the owner runs the DNS directly instead of relying on a hosting or DNS provider. An older registration date is often seen as a sign of an established website, although age alone says nothing about who owns it today. Status flags such as transfer or delete locks are set by the registrar or registry to protect a domain from unauthorised changes.
