Your box moved.
The name didn't.

Dynamic DNS for the machine under your desk. Point a hostname at your home IP, and we keep it pointed there — plus you can be alerted when your updater goes quiet.

01 yourname.sploink.org
02 yourname.floatypotato.com
03 yourname.tinypotato.org
04 yourname.indirection.org

what you get

Everything a DDNS provider should do, plus the part nobody else does.

Free monitoring

Every hostname gets uptime monitoring at no cost. Know when your services go down before your users do.

No confirmation nag

No 30-day confirmation emails. No "click here or we delete your record" messages. Set it and forget it.

Works with your router

DynDNS2 works out of the box with ASUS, Netgear, TP-Link, UniFi, pfSense, Synology, and more.

Names worth saying

sploink.org, floatypotato.com, tinypotato.org, indirection.org. Your hostname is a conversation starter.

Scoped tokens

Give your router only the permissions it needs. A leaked token can't touch your other hostnames.

Simple setup

One curl command, one cron job, done. Or use the dashboard for point-and-click management.

Full REST API

Everything the dashboard does, the API does. Automate the lot. Swagger docs included.

Open update log

Every IP change, when it happened, what triggered it, and whether it worked.

Certbot plugin

Wildcard TLS certificates via DNS-01 validation.

MX/TXT/SRV records

Host email, set SPF and DKIM, or advertise services from your hostname.

Bring your own domain

Use vpn.yourdomain.com instead of ours. We manage the DNS.
