sdyuanzeng.com

According to its WHOIS record, SDYUANZENG.COM was created on January 15, 2010 and expires on January 15, 2023. That makes the domain about 16 years old. It is registered through Alibaba Cloud Computing (Beijing) Co. Ltd. (IANA ID 420) and is past its expiry date. DNS is served by dns7.hichina.com and dns8.hichina.com. Nameservers decide where a domain's DNS is hosted, so a change of nameservers usually means the website or email moved to a new provider. Changes to the registrant organisation can point to a sale, a merger or simply an update of company details. 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. 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. Public WHOIS records can show the registrant organisation and country, while many owners now hide personal details behind privacy services.
