       TIL about dynamic DNS (DDNS)https://datatracker.ietf.org/doc/html/rfc2136This provides a standard API to dynamically update DNS records.That's particularly handy to update the TXT and SRV records. Quite a few integrations already exist. For instance for prosody: https://modules.prosody.im/mod_dnsupdateOn the server side, it's natively supported by knot. Nsd does not support that natively, but you can use an external daemon (dyndnsd) to expose the DDNS api and update the text zone files.

       @picnoir convenient also when your box doesn’t provide you with a fixed ipv4 address but accepts to update your dns record each time it changes ip

       @picnoir We (geeknode) use this tu update TXT record to generate our TLS certs. We have multiple nodes and they need TLS certs for thein names but also for a shared name : each server get its XXX.geeknode.org cert but also each server get irc.geeknode.org . We could use a wildcard cert and move it from machine to machine but it's way better/safer/easier like this.
