Today I launched, a domain where every IPv6 address has its own AAAA record. For example, resolves to 2001:db8:8000::1. See on how it works in detail.


Recently I needed a valid TLS certificate for a local service that didn’t have its own DNS record. Unfortunately Let’s Encrypt doesn’t certify IP addresses, so I had to come up with a solution. Now you can simply request certificates for <converted IPv6 address> and you’re done.


The site runs a custom DNS server implementation that automatically converts queried domain names to their corresponding IPv6 addresses. The software also supports reverse lookups. See for details.


This is a hobby project, don’t rely on it’s availability.
