Built by people who
run the same hardware.
Every feature here exists because we wanted it on our own boxes first.
what makes us different
Uptime monitoring on every hostname, at no cost
No other DDNS provider bundles monitoring. Because we run both the DNS layer and the monitoring layer, we can do things a standalone monitor cannot: suppress alerts during our own zone maintenance, spot a stale client before its IP changes, and know exactly when propagation should have finished.
No confirmation nag
Some providers delete your hostname unless you click a confirmation link every 30 days. We do not send those emails, and your hostname does not need periodic proof that you still want it.
Three ways to update, so every client works
DynDNS2 for routers, a plain URL for cron and curl, and a full REST API for everything else. All three from day one.
Verified against ddclient and inadyn. Any client that speaks DynDNS2 should work — if yours needs a custom server and will not take one, tell us.
everything else
The rest of what you get.
Names worth saying
sploink.org, floatypotato.com, tinypotato.org, or indirection.org. Your hostname gets read every time it turns up in a config file or a forum post.
Scoped API tokens
Restrict a token to specific hostnames and record types. Your router gets one that can only update its own A record.
Server-side IP detection
Don't know your public IP? Don't send one. We read it from the request. There's a free /ip endpoint for scripts too.
Full update log
Every IP change: what changed, when, how it arrived (DynDNS2, API, or curl), and whether it worked.
Dashboard and API
Point-and-click in the browser, or automate the same operations over REST with Swagger docs.
IPv6
Full AAAA support, for dual-stack, IPv6-only, and DS-Lite setups. Prefix tracking is on the roadmap.

Not shipped yet.
Wildcard DNS
*.mybox.sploink.org resolves to your IP, so one hostname covers every service behind your reverse proxy.
Certbot / ACME
Wildcard TLS certificates via DNS-01 validation, with a certbot plugin for Let's Encrypt.
MX/TXT/SRV records
Host email, set SPF and DKIM, or advertise services straight from your hostname.
Bring your own domain
Use vpn.yourdomain.com instead of ours. We manage the DNS for it.
Three minutes, start to finish.
Three hostnames free. No credit card, and no confirmation emails.
