Does Lets Encrypt allow the same Wildcard certificate across multiple physical machines/IPs?

Hello!

From the FAQ (FAQ - Let's Encrypt), I understand that Let's Encrypt issues Wildcard certificates.

However, I just wanted to check to be sure - am I allowed to use a single Wildcard certificate across multiple IPs (and also physical machines)?

I'm asking in particular because of an old Server Fault question I came across, where GeoTrust apparently required additional licenses if multiple physical servers were used, so I just want to double-check that Let's Encrypt do allow the same Wildcard being used over multiple IPs and/or physical servers.

Thank you!

You are free to re-use the certificate for multiple machines. You can even use it in the dovecot server software to secure IMAP and POP connections (and sendmail, and ...)
