Cloudflare v6 DDNS

Something like DDNS, but from scratch, and in rust?

• Application
  • should update all DNS records on IP change
  • should run every minute?
    • should update every AAAA record (assuming I am only going to have IPv6 records configured for local setup)
    • Bad assumption - maybe a list of domains?
      • Workaround: use CF’s description feature, add something like update:local:ipv6
      • CF API provides way to retrieve records containing specific content in comment - https://developers.cloudflare.com/api/operations/dns-records-for-a-zone-list-dns-records (comment.contains)
    • CF API handle pagination
  • Should store data in database?
  • Should use 1.1.1.1 Purge API to purge the old DNS records
