We see that #LetsEncrypt is now experimentally issuing IPv4 and IPv6 certs! (https://letsencrypt.org/2025/07/01/issuing-our-first-ip-address-certificate/).

This is fantastic news for people who want to set up their own #DOH or #DOT servers that support automatic encryption upgrade (DDR - https://datatracker.ietf.org/doc/rfc9462/).

We look forward to this being put into production. We wish the expiry time was a bit longer - maybe a new profile with 30 day validity? But in any case - great to see this happening. 👏
