The domain DUIPXENT.COM was first registered on September 29, 2020 and its current term runs until September 29, 2028. Its age is about 6 years. Its sponsoring registrar is CSC Corporate Domains, Inc. (IANA ID 299), and the domain is active. Public WHOIS names Sanofi Biotechnology as the registrant organisation, with France as the country. 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. Privacy services replace the owner's contact details in the public record with those of a proxy, which is common for personal registrations. 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. 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. Managed DNS providers are often used for speed, security and protection against attacks. A registrar transfer moves the management of a domain from one company to another without changing the domain name itself. Domains that are not renewed before their expiry date normally enter a grace and redemption period before they can be registered again.
We have collected 16 historical WHOIS snapshots for DUIPXENT.COM. The most recent capture is from October 31, 2026. Each snapshot is a dated copy of the public WHOIS record as it looked when it was collected. Investigators use dated records to establish who controlled a domain at a specific point in time. A long history with few changes usually points to a stable owner, while frequent changes can signal a transfer or a resale. Snapshots are collected over time, so the gaps between them depend on how often the record was checked. Comparing snapshots makes it easy to see when the registrar, nameservers or status of a domain changed. The snapshot list below shows every capture we hold, newest first.
