Drop catching is the practice of registering a domain name within seconds of it being deleted from the registry. When a domain completes the full expiration cycle and enters pending delete, it gets purged from the registry at a specific time. Drop catchers use automated systems to submit registration requests at that exact moment, racing to grab the domain before anyone else.
How drop catching works
It's a speed game. Registries like Verisign (.com, .net) delete domains in batches, usually once per day. The exact deletion time isn't published, so drop catching services maintain persistent connections to the registry and fire registration requests the instant they detect the domain is free.
A single manual registration attempt won't cut it. Professional drop catching services send hundreds of simultaneous requests through multiple registrar accounts. Services like DropCatch and Catched have built entire businesses around this infrastructure. They maintain fast network connections to registries and optimize every millisecond of the registration process.
When a service successfully catches a domain, it typically goes to a domain auction among users who placed backorders. If only one person wanted it, they get it at the base fee. If multiple people wanted it, they bid against each other.
Why it matters for expired domains
Drop catching is how the most valuable expired domains get acquired. A domain with 20 years of history and strong backlinks won't sit unclaimed for long. Within seconds of deletion, multiple services are fighting over it. As an individual buyer, you can't compete on speed. But you can use CatchDoms to monitor which domains are being auctioned across DropCatch and Catched, then bid on the ones that match your criteria.
