SSL Certificate for IP Address

Can an SSL Certificate Be Issued For an IP Address?  

The answer is ‘Yes.’ An SSL certificate can be issued for a public IP address. 

These are the rules and requirements to get an SSL certificate for an IP address: 

  • SSL can be issued for a public IP address.  
  • Your organization must own that particular IP address. In other words, the IP address must be exclusively assigned to your organization (not to the web hosting company). 
  • A certificate authority must be able to verify your IP ownership under an IP WHOIS lookup. Your organization’s name, physical address, phone number, and email id must be shown in the  IP WHOIS lookup.  
  • You must buy an Organization Validated (OV) SSL certificate to secure an IP address. 
  • Documents Required: Check here.  
  • Both OV Single domain and OV multi-domain SSL certificates can be used for an IP address.  
  • You can write an IP address in the Common Name (CN) or a Subject Alternative Name (SAN) field (if you have chosen a multi-domain SSL). 
  • All version of Windows will support the SSL if you specify the IP address as the Common Name (CN). Windows 8.1 and earlier versions will not support the SSL certificate if you specify an IP address as a Subject Alternative Name (SAN). 
 Common Name (CN) Subject Alternative Name (SAN) 
Windows 8.1 and earlier  Yes No
Windows 10   Yes Yes
  • An SSL certificate can’t be issued for Reserved IP addresses (RFC 1918 and RFC 4193 range)/ private IP addresses (IPv4, IPv6), Intranet for Internal Server Name, local server name with a non-public domain name suffix. 
  • Domain Validated (DV) and Extended Validated (EV) SSL are not permitted to issue for an IP address.  

Can I Get an SSL for Private IP? 

No. Since 2016, the CA/Browser Forum made SSL certificates for private IP/reserved IP and local server name with a non-public domain name suffix invalid and asked certificate authorities to revoke any such SSL certificates. Because such reserved IP addresses and local server names (intranet) are not unique, they are easy to impersonate by attackers to commit man-in-the-middle attacks and get unauthorized access to the data. Hence, publicly trusted certificate authorities can no longer secure such IPs. You can get a self-signed SSL certificate for private IPs and intranet addresses, though.
