5. Domain name
There are interoperability issues using IP-address for service, and therefore the requirement in STM is that the domain shall be properly registered and registered in DNS.
The server certificate contains field for the domain where the service is located. This must be a domain name and not an IP address.
CN=Common Name
SAN=Subject Alternative Name (RFC 2818)
Example:
The URL to the service is
The CN=smavis.stmvalidation.eu
