mailbook.app

According to its WHOIS record, MAILBOOK.APP was created on October 30, 2018 and expires on October 30, 2027. This gives it about 8 years of history. It is registered through Key-Systems GmbH (IANA ID 269) and is active. The registrant country on record is Netherlands. 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. Registrars are the companies accredited to sell and manage domain names, and the sponsoring registrar is the one currently responsible for this name. Public WHOIS records can show the registrant organisation and country, while many owners now hide personal details behind privacy services. A registrar transfer moves the management of a domain from one company to another without changing the domain name itself. Managed DNS providers are often used for speed, security and protection against attacks. The creation date shows when the name was first registered, while the expiry date shows how long the current registration has been paid for. Domains that are not renewed before their expiry date normally enter a grace and redemption period before they can be registered again. Privacy services replace the owner's contact details in the public record with those of a proxy, which is common for personal registrations. 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. 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. Changes to the registrant organisation can point to a sale, a merger or simply an update of company details. Status flags such as transfer or delete locks are set by the registrar or registry to protect a domain from unauthorised changes. An older registration date is often seen as a sign of an established website, although age alone says nothing about who owns it today.

In the period from November 15, 2022 to October 31, 2026, 36 fields of the record were modified. The domain moved from Key-Systems LLC to Key-Systems GmbH. Status flags were updated: autoRenewPeriod and ok were removed. It was renewed: the expiry date went from October 30, 2023 to October 30, 2027.

The Whois Data Center archive contains 9 historical WHOIS snapshots for MAILBOOK.APP. The most recent capture is from October 31, 2026. 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. 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. Buyers often review the history of a domain before purchasing it, to see past owners and registrars. Each snapshot is a dated copy of the public WHOIS record as it looked when it was collected. Historical records are useful for due diligence, brand protection and investigating the background of a website. Security teams use WHOIS history to spot suspicious ownership changes and to link related domains. These records help track changes in registration details, ownership signals and DNS over time.
