Examples

Preview record changes that would be made

dns-updater --api-key key_with_write_access -d @.example.com -d subdomain.example.com

Update records after verifying it looks good

dns-updater --api-key key_with_write_access -d @.example.com -d subdomain.example.com -A

Update records and also skip 10 second warning on startup

dns-updater --api-key key_with_write_access -d @.example.com -AS

Update records now and also skip 10 second warning on startup, and then keep updating records every 30 minutes

dns-updater --api-key key_with_write_access -d @.example.com -ASm 30

WAN IP Source

A text file is created on startup in the working directory that contains a list of api endpoints for querying the current WAN IP. It's then read before every record update.

By default the following endpoints are included:

• https://api.seeip.org
• https://api64.ipify.org
