In short
Drop-catching is the re-registration of a domain the moment it becomes publicly free after its period ends. Because several people often access it at once, it is automated. How predictable it is depends on whether the registry publishes a fixed drop time and drop lists.
How it differs from a backorder
With a backorder you place the order in advance; drop-catching emphasises the registration moment itself. In practice, services combine both.
When drop-catching works well
It is most predictable for extensions with a published, fixed drop time and drop lists — such as .uk (fixed UTC times) or .se (release lists). For extensions without a fixed drop, e.g. .at, it is less calculable.
Success factors
- Knowing the exact release time (if published).
- Fast, automated registration.
- Realistic expectations: for popular names, milliseconds decide.
