A single Wildcard SSL certificate can secure multiple websites. Typically, a standard secure server SSL certificate is issued to a single FQDN. This means that the certificate can only be used on the exact domain to which it has been issued. The Wildcard SSL option, when activated, allows you to circumvent this restriction by receiving a Wildcard SSL Certificate issued to “*.domain.com”. The (*) character replaces a fixed sub-domain with a variable one.
Public IP Addresses
Issuing an SSL Certificate to a Public IP Address
An SSL certificate is typically issued to a Fully Qualified Domain Name (FQDN) such as “https://www.domain.com”. However, some organizations need an SSL certificate issued to a public IP address. This option allows you to specify a public IP address as the Common Name in your Certificate Signing Request (CSR). The issued certificate can then be used to secure connections directly with the public IP address
Verify Domain Ownership – Approver Email Method
Domain SSL Certificates are authenticated using the Approver E-Mail verification system.
The following email addresses can be used for domain approval:
The current whois admin contact
The current whois technical contact
You must have access to one of these email accounts on the SSL domain to be able to receive the SSL certificate.
The Common Name is typically composed of Host + Domain Name and will look like "www.example.com" or "example.com".
