AGP (Add Grace Period)
AGP is the acronym for Add Grace Period and refers to the 5 days after the initial registration of a domain name at which time a registrar used to be able to cancel any registration without incurring an expense. The AGP was initially put in place to protect registrars from incurring an expense when domains are registered with bad payments, credit card fraud, etc. Due to substantial abuse of the AGP with domain kiting and domain tasting, ICANN and several registries began limiting the number of domains any single registrar can delete without incurring additional fees which greatly reduced this practice.
