Drop catching

Drop catching is registering an expired domain name the instant the registry deletes it, using specialist services that send registration requests through many registrar connections at the moment of deletion.

Drop catching, explained

When a .com name finishes its 30-day redemption period and 5-day pending delete, Verisign deletes it in the daily drop, and the first valid registration request to arrive wins. An ordinary registrar is rarely fast enough, so services such as DropCatch operate large numbers of ICANN-accredited registrars, each with its own connection to the registry, and fire requests in the opening seconds. Some registrars, Dynadot among them, also take backorders.

You place a backorder on the name. Some services charge only if the catch succeeds and others take payment up front, so check each one's terms. If more than one customer backordered the name, the catching service usually holds a short private auction among them, so a popular name can end far above the opening price. Many valuable expiring names never drop at all, because the registrar sells them in its own expiry auction or a partner's pre-release auction during the grace period.

Do the due diligence before the auction, not after: search for trademark conflicts, check the name's history in the Wayback Machine, and find out whether its traffic or backlinks came from spam. Set a maximum bid tied to realistic resale value. The common mistake is treating a caught name as a bargain because the opening price was low; competition among backorderers often pushes good names toward their wholesale market value.

Rules differ outside generic TLDs: country codes such as .ai, .io and .co run their own deletion and auction processes. AI has crowded the screening side. Software can score an entire day's delete list in minutes, so the obvious names attract many bidders, and the remaining edge is human judgment about end-user demand and legal risk.

Example. Three investors backorder the same expiring .com at one drop-catch service; the service catches it at deletion and runs a short auction among the three.
