+# IPv64
+
+## Configuration
+
+### Example
+
+```json
+{
+  "settings": [
+    {
+      "provider": "ipv64",
+      "domain": "domain.com",
+      "key": "key",
+      "ip_version": "ipv4",
+      "ipv6_suffix": ""
+    }
+  ]
+}
+```
+
+### Compulsory parameters
+
+- `"domain"` is the domain to update. It can be `example.com` (root domain) or `sub.example.com` (subdomain of `example.com`).
+- `"key"` that you can obtain [here](https://ipv64.net/account)
+
+### Optional parameters
+
+- `"ip_version"` can be `ipv4` (A records), or `ipv6` (AAAA records) or `ipv4 or ipv6` (update one of the two, depending on the public ip found). It defaults to `ipv4 or ipv6`.
+- `"ipv6_suffix"` is the IPv6 interface identifier suffix to use. It can be for example `0:0:0:0:72ad:8fbb:a54e:bedd/64`. If left empty, it defaults to no suffix and the raw public IPv6 address obtained is used in the record updating.
