Can I use letsencrypt on an IP address if I don't have a domain name?

Help

Please fill out the fields below so we can help you better.

My domain is: an ip address

I ran this command:

It produced this output:

My operating system is (include version): ubuntu-server 16.04

My web server is (include version):

My hosting provider, if applicable, is: home cable modem

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

I realize that my IP is likely to change from time to time, but I could just issue another certificate at that time? It’s just a small server located in my house so I can share files over the web with my parents and friends.

Nope, Let’s Encrypt doesn’t issue certificates for IP addresses, only domain names.

But there are many free domain name services around there :slight_smile:
