1 Cert for IP + Domain with Let's Encrypt + Caddy + acme.sh
Learn how to issue one short-lived Let's Encrypt cert that covers your domain and IPs, then load it in Caddy via acme.sh for HTTP/3-ready TLS.
We've Issued Our First IP Address Certificate
letsencrypt.orgUpdate: January 15, 2026 Six-day and IP address certificates are now generally available. See 6-day and IP Address Certificates are Generally Available for details. Since Let’s Encrypt started issuing certificates in 2015, people have repeatedly requested the ability to get certificates for IP addresses, an option that only a few certificate authorities have offered. Until now, they’ve had to look elsewhere, because we haven’t provided that feature. Today, we’ve issued our first certificate for an IP address, as we announced we would in January. As with other new certificate features on our engineering roadmap, we’ll now start gradually rolling out this option to more and more of our subscribers.
