US 9,521,138 B2 · System for domain control validation

Abstract

A system and method for domain control validation is presented. At a certificate authority a request is received. The request includes a certificate signing request and a first Internet protocol address. The certificate signing request identifies a domain and a certificate. A second Internet protocol address for the domain is retrieved from a domain name system. When the first Internet protocol address is the same as the second Internet protocol address, the certificate is signed, and the signed certificate is transmitted to a requester of the request. When the first Internet protocol address is not the same as the second Internet protocol address, the certificate signing request is rejected.
