Let's Encrypt doesn't issue certificates for IP addresses. ZeroSSL does, it was fairly straightforward to get a free one through their website when I tried many months ago.
The answer is 'Yes. ' An SSL certificate can be issued for a public IP address. These are the rules and requirements to get an SSL certificate for an IP address: SSL can be issued for a public IP address.
Let's Encrypt certificates are standard Domain Validation certificates, so you can use them for any server that uses a domain name, like web servers, mail servers, FTP servers, and many more. Email encryption and code signing require a different type of certificate that Let's Encrypt does not issue.
Let's Encrypt issues domain-validated certificates. The certificates must be attached to at least a domain name.
Moreover, Let's Encrypt policy is to not issue SSL certificates for IP addresses, therefore you won't be able to use the certificate to a server that it's reachable only thought its IP address.
Technically, you can install it. But when connecting to the IP address, the clients will display a certificate name mismatch error.
