Domain drop catching
Domain drop catching, also known as domain sniping, is the practice of registering a domain name once registration has lapsed, immediately after expiry.
When a domain is first registered, the customer is usually given the option of registering the domain for one year or longer, with automatic renewal as a possible option. Although some domain registrars often make multiple attempts to notify a registrant of a domain name's impending expiration, a failure on the part of the original registrant to provide the registrar with accurate contact information makes an unintended registration lapse possible. Practices also vary, and registrars are not required to notify customers of impending expiration. Unless the original registrant holds a trademark or other legal entitlement to the name, they are often left without any form of recourse in getting their domain name back. It is incumbent on registrants to be proactive in managing their name registrations and to be good stewards of their domain names. By law there are no perpetual rights to domain names after payment of registration fees lapses, aside from trademark rights granted by common law or statute.
Redemption Grace Period (RGP)
The Redemption Grace Period is an addition to ICANN's Registrar Accreditation Agreement (RAA) which allows a registrant a number of days to reclaim their domain name for a number of days after it expires. This length of time varies by domain, and is usually around 30 to 90 days. Prior to the RGP, individuals could easily engage in domain sniping to extort money from the original registrant to buy their domain name back.
Once time is up, the domain status changes to a "redemption period" when an owner is required to pay a fee (usually around $100 - $250 (enom)) to re-activate and re-register the domain. ICANN's RAA  requires registrars to delete domain registrations once a second notice has been given and the RGP has elapsed. At the end of the deletion phase of 5 days, the domain will be dropped from the ICANN database.
Drop Catch Services
For particularly popular domain names, there are often multiple parties anticipating the expiration. Competition for expiring domain names has since become a purview of drop catching services. These services offer to dedicate their servers to securing a domain name upon its availability, usually at an auction price. Individuals with their limited resources find it difficult to compete with these drop catching firms for highly desirable domain names.
Retail registrars such as GoDaddy or eNom retain names for auction through services such as TDNAM or Snapnames through a practice known as domain warehousing. Drop catch services are performed by both ICANN-accredited registrars and non-accredited registrars.
