Why closetserver.com?

Everything you need from a DDNS provider, plus things nobody else offers.

Free Monitoring
Every hostname gets uptime monitoring at no cost. Know when your services go down before your users do.
No Nag, No Expiry
Your hostname is yours. No 30-day confirmation emails. No "click here or we delete your record" threats.
Works With Your Router
DynDNS2 protocol support works out of the box with ASUS, Netgear, TP-Link, UniFi, pfSense, Synology, and more.
Fun Domain Names
Pick from sploink.org, floatypotato.com, tinypotato.org, or 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 you can do in the dashboard, you can do via API. Automate everything. Swagger docs included.
Open Update Log
See every IP change, when it happened, what triggered it, and whether it succeeded. Full transparency.
