namefi-dyndns-with-ddclient

Use when a user wants to expose a locally-developed service on a real hostname without a static IP using ddclient — set up dynamic DNS with an existing ddclient install, write or debug a ddclient.conf for Namefi's DynDNS2 endpoint, run ddclient as a daemon/service, read its output, or map a Dyn return code (good/nochg/badauth/nohost/numhost/abuse) to a fix. Covers both a VPS (single public IP) and a homelab behind NAT.
