I was curious as to how a certificate could be issued to an IP address and not a domain (I didn't know that such a thing was possible), and learned this:
X509v3 Subject Alternative Name:
DNS:cloudflare-dns.com, DNS:*.cloudflare-dns.com, DNS:one.one.one.one, IP Address:1.1.1.1, IP Address:1.0.0.1, IP Address:162.159.36.1, IP Address:162.159.46.1, IP Address:2606:4700:4700:0:0:0:0:1111, IP Address:2606:4700:4700:0:0:0:0:1001, IP Address:2606:4700:4700:0:0:0:0:64, IP Address:2606:4700:4700:0:0:0:0:6400
You can inspect the certificate yourself with:
openssl s_client -showcerts -connect 1.1.1.1:443 < /dev/null | openssl x509 -text -noout
Too bad Let's Encrypt will not issue certificates for IP's at this time.
