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.

Wildcard DNS

*.mybox.sploink.org resolves to your IP, so one hostname covers every service behind your reverse proxy.

in development

Certbot / ACME

Wildcard TLS certificates via DNS-01 validation, with a certbot plugin for Let's Encrypt.

planned

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.
