Registered on April 2, 2021, 81LBD.NET is paid up until April 2, 2022. That is around 5 years of continuous registration. Hefei Juming Network Technology Co. Ltd (IANA ID 3758) is the registrar of record, and the domain is currently past its expiry date. Status flags block unauthorised transfer. Its nameservers are s1.mb.cn and s2.mb.cn. 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. Renewals are usually made for one to ten years at a time, so an expiry date far in the future shows a long-term commitment to the name.
