Google Domains supports Dynamic DNS. That is great since my domain and Dynamic DNS information can come from the same provider.
For Dynamic DNS to work, I usually need the following info:
- Update URL
- Hostname
- Username
- Password
Of the four variables above, I know three. From Google, I can get Username and Password. I also know my server's hostname. However, I do not know the Update URL. In other words, I do not know to which Google server I should send the information to in order to update my IP Address.
Which Google Domains server should I notify about my IP Address change?
https://domains.google.com/nic/update
. If you're not using a client to perform the update, then check the API docs on the format to make the request.
