Features

Three hosts for free

Sign up with just an email address and keep up to three hosts. You set the password from the link in the email.

Works with DiCE

The DiCE plug-in already out there works as it is.

From routers and NAS

dyndns2-compatible updates from routers, NAS and ddclient, for both IPv4 and IPv6. Up to 20 hosts in one request.

Quick to update

Hosts have a TTL of 120 seconds, so a new IP address is picked up soon after it changes.

My page

Add and remove hosts and update with your current IP. Setup examples for DiCE, routers, ddclient and plain URLs are shown for each host.

Free tools and API

Check your IP address and whether a port is open. Programs can use the API (/api/ip, /api/port-check).
