+# Dynamic DNS
+
+## Setup
+
+Most cloud providers / ISPs will charge you extra for a static IP address. If you're
+not hosting a highly reliable homeserver you can workaround this via dynamic DNS. To
+set this up, you'll need to get the username/password from your DNS provider. For
+google domains, this process is described [here](https://support.google.com/domains/answer/6147083).
+After you've gotten the proper credentials you can add the following config to your inventory/host_vars/matrix.DOMAIN/vars.yml:
+
+```
+matrix_dynamic_dns_domain_configurations: |
+  {{
+    [{'provider': 'domains.google.com', 'protocol': 'dyndn2', 'username': 'XXXXXXXXXXXXXXXX', 'password': 'XXXXXXXXXXXXXXXX', 'domain': matrix_domain}]
+  }}
+```
