Lets Encrypt have now started to issue certs for public facing IP addresses as well as their famed free TLS and DV SSL Certs.
This is an absolute Game changer!!

Now you can simply run a site without a domain name, with SSL. Whilst I don't think that's the real takeaway here, and purpose, It is dead handy for when you spin up a new server, and haven't got DNS fully functional for your hostname yet. So in theory, you could buy a server, install directadmin and not have to worry about using DA's DNS and temp link to log in to your panel securely. You could simply use the servers given IP securely, out of the box. It's something DA would have to implement, unless you set it up by obtaining certs yourself first before install DA.
I have to add, there's 2 caveats here,
You CANNOT use one of these certs with a local IP for example 10.0.10.272 or 192.168.0.100
Certs are aggressively renewed, and expire after 7 days, so daily issuance is recommended (I guess as it's only supposed to be a temp fix)
This has so much potential!
IPv4 and IPv6 supported, Pics incoming...!
Edit - Here's pics showing SSL on IPs
