Low-TTL records served by our own authoritative DNS. A change is live within a minute.
IPv4 + IPv6 together
A and AAAA side by side; update both in a single request.
Scoped credentials
Account tokens for your fleet, per-hostname secrets for the router you don't fully trust. Everything stored hashed.
Full audit trail
Every update attempt logged — result, IP, client, user-agent — right in your dashboard.
Self-hosted, your rules
Your zone, your database, your server. No third party between your name and your network.
The whole integration

curl -u x:$TOKEN "https://dyndnsip.com/api/v1/update?hostname=you.dyn.dyndnsip.com"
Free for homelabs.
Serious for fleets.
Full pricing Questions, answered
What is dynamic DNS?＋
Home and small-office connections get a new IP address whenever the ISP feels like it. Dynamic DNS keeps a fixed hostname pointed at that moving target, so your VPN, camera, NAS or game server stays reachable at the same name.
Which routers and clients are supported?＋
Anything that speaks the dyndns2 protocol: MikroTik RouterOS, ASUS routers, pfSense/OPNsense, DD-WRT, ddclient, inadyn — or a one-line curl in a cron job. Setup guides for each are in the docs.
How fast do changes propagate?＋
Records carry a 60-second TTL and are served by our own authoritative nameservers, so resolvers worldwide pick up a new IP within about a minute.
Is the free tier actually free?＋
Yes — 50 hostnames, IPv4 + IPv6, the full API and update history. Paid plans exist for people who need hundreds of names.
