Server Name Indication (SNI) allows the web servers and network appliances to safely host multiple TLS/SSL certificates for multiple sites, all under a single IP address and port number. Instead of requiring a different IP address for each SSL site, you can use SNI to install and configure multiple SSL sites to one IP address.
Load balancers with support for SNI automation
Web servers with support for SNI automation
SNI certificate automation can only happen on HTTPS bindings. To request additional certificates for an IP address/domain, you must have a TLS/SSL certificate installed on the IP/port of the sever or appliance.
For automation using Microsoft IIS server
In your CertCentral account, in the left main menu, go to Automation > Automated IPs.
On the Automated IPs page, find the common name for the IP/port for which you want an additional certificate.
In the Action column, select Add SNI.
On the automation request page, enter the common name and server name that you want the certificate to secure based on the automation location.
Provide the other required information and schedule the certificate automation.
When the automation is complete, the certificate for the requested site will be issued and installed to the IP address and port.
