Shared Hosting?

[thomasc]

Hello,

We, at PulseHeberg.com, are also interested to bring free Let's Encrypt SSL certificates available to our shared hosting's customers.
I'm also interested to discuss with a LE staff member about any integration of Let's Encrypt.

Hi @lew, you don't need an individual IP address because of Subject Alternative Names (SAN), which let a single certificate be valid for many different domains, and likely also because of Server Name Indication (SNI), which lets a client indicate which domain name it's trying to connect to when beginning the TLS session. Each of these has some limitations: there's a maximum number of SAN names per certificate, SANs reveal in an obvious way exactly which sites may be hosted on the same server, and SNI isn't supported by some old client software.

If I correctly understood your point, you're saying that a single certificate can be used by multiple domains on a single host. But what about different domains, each one having a different LE SSL certificate on a single host (with a single IP address). It is possible with Let's Encrypt or it requires a private IP address for each domain?

Best regards,
Thomas Cardonne.
