Your IP is hosted on a private ovh server. The IP is not used for any other purpose than to offer the service.

Yes, ZapDNS is 100% private, we do not use your information for any other purpose than to offer you the service.

My name is Kevin Fernández and my purpose here is to offer different web services focused on user privacy, always using free software.

You can simply login to the website and manage your subdomain and IP address there or you can use the simple HTTP API to update your IP with a script or dynamic DNS client.

The easiest way to keep your mapping up to date is to add the following line to your crontab which will update your IP every three hours:

0 */3 * * * curl -u 'USERNAME:PASSWORD' https://zapdns.xyz/update

You can use ddclient to keep your IP address up to date with the following config:

server=zapdns.xyz, \
protocol=dyndns2,   \
login=USERNAME,     \
password=PASSWORD   \
SUBDOMAIN.zapdns.xyz

Routers running DD-WRT can update your IP address by using the built in dynamic DNS settings found under Setup → DDNS. Other routers may also work but are untested.
