Secure only – When this type of dynamic update is selected, only the computers that are members of the DNS domain can register themselves with the DNS server. The DNS server automatically rejects the requests from the computers that do not belong to the domain. This protects the DNS server from getting automatically populated with records of unwanted, suspicious and/or fake computers.
