The Internet security community is phasing out the use of intranet names and IP addresses as primary domain names or Subject Alternative Names (SANs) in SSL certificates. This is an industry-wide decision, not one specific to our company.
As of July 1, 2012, we no longer accept new requests, rekeys or renewals for SSL certificates that contain intranet names or IP addresses and are valid beyond Nov. 1, 2015. In addition, we do not support SSL certificates that secure public IP addresses or IPv6 addresses.
An intranet name is the name of a private network, such as server1, mail or server2.local, that public Domain Name Servers (DNS) cannot access. An IP address is a string of numbers, such as 22.214.171.1240, that defines a computer's location.
Why the change?
To create a safer online environment, members of the Certificate Authorities Browser Forum met to define implementation guidelines for SSL certificates. As a result, effective October 1, 2016, Certification Authorities (CAs) must revoke SSL certificates that use intranet names or IP addresses.
