Due to a CA/Browser Forum guidelines, all CA’s are required to revoke any valid SSL certificates whose Subject Alternative Name (SAN) extension and/or common name field contain a Reserved IP Address or Internal Name by October 1, 2016.
If your SSL certificate is still valid on or after October 1, 2016 and contains an Internal Name or Reserved IP address in the SAN extension and/or common name, the certificate will automatically be revoked by RapidSSL between September 15, 2016 to September 28, 2016.
For more information on this change, please refer to the following CA Browser Forum resources.
- CA-Browser Forum BR 1.3.3 (Section 18.104.22.168.1)
