Speaks the dyndns2 protocol — works with the gear you already own
Built for people who run their own infrastructure and want it to just work.
60-second TTLs and a live database read mean an update is visible on the very next query. No waiting for caches to expire.
The exact protocol MikroTik, pfSense, UniFi and ddclient already speak. Paste a URL, or fill in five fields. Done.
A and AAAA records on every hostname. Dual-stack from day one — push both in a single update.
Flip one switch and *.yourname resolves to the same address. Perfect for self-hosted apps behind one IP.
Each hostname carries its own update secret. Compromised a device? Rotate the token without touching the others.
Every update — who, when, from where, and the result code — recorded per hostname. Catch a misbehaving client fast.
Pick a label under polfence.net, dyn.polfence.io or home.polfence.dev. It's yours instantly.
