k520.net

Registered on December 13, 2013, K520.NET is paid up until December 13, 2023. This gives it about 12 years of history. Alibaba Cloud Computing (Beijing) Co. Ltd. (IANA ID 420) is the registrar of record, and the domain is currently past its expiry date. Its nameservers are expirens4.hichina.com and expirens3.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. 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. Registry locks add an extra layer of protection for valuable names, because changes then need manual confirmation by the registry. Managed DNS providers are often used for speed, security and protection against attacks. Public WHOIS records can show the registrant organisation and country, while many owners now hide personal details behind privacy services.

The Whois Data Center archive contains 11 historical WHOIS snapshots for K520.NET. The newest snapshot was taken on January 28, 2023. Security teams use WHOIS history to spot suspicious ownership changes and to link related domains. Historical records are useful for due diligence, brand protection and investigating the background of a website. Comparing snapshots makes it easy to see when the registrar, nameservers or status of a domain changed. Snapshots are collected over time, so the gaps between them depend on how often the record was checked. The snapshot list below shows every capture we hold, newest first. A long history with few changes usually points to a stable owner, while frequent changes can signal a transfer or a resale. Investigators use dated records to establish who controlled a domain at a specific point in time.
