添加宽限期(AGP)是ICANN[[registry-agreement|注册局协议]]中规定的5天窗口期,在此期间[[registrar|注册商]]删除新注册域名可从[[registry-operator|注册局]]获得注册费全额退款。AGP最初旨在允许注册商无损失地撤销计费错误或客户取消操作,但却被[[domain-tasting|域名品鉴]]行为系统性滥用。2008年,ICANN将AGP退款限制为注册商每月总注册量的10%或50个域名(以较大者为准),从而有效终结了大规模品鉴行为。
示例
A registrar that accidentally registers the wrong domain on a customer's behalf can delete it within the 5-day AGP and receive a full credit — the customer is refunded without the registrar absorbing a net loss.
