There are two operational modes: 1. When you enable the sensor with minimal configuration, it will query the [OpenDNS](https://www.opendns.com/) nameservers with the hostname `myip.opendns.com`, which will resolve to your external/public IP address. 2. If you specify a `hostname`, a regular DNS lookup will be performed, providing you the IP the hostname resolves to. You may also override the nameserver that is being used by setting the `resolver` parameter to any nameserver you like. To enable this sensor, add the following lines to your `configuration.yaml` file: ```yaml # Example configuration.yaml entry sensor: - platform: dnsip ``` Configuration variables: - **hostname** (*Optional*): The hostname for which to perform the DNS query. Default: `myip.opendns.com` (special hostname that resolves to your public IP) - **resolver** (*Optional*): The DNS server to target the query at. Default: `208.67.222.222` (OpenDNS) - **ipv6** (*Optional*): Set this to `true` or `false` if IPv6 should be used. When resolving the public IP, this will be the IP of the machine where Home Assistant is running on. - **resolver_ipv6** (*Optional*): The IPv6 DNS server to target the query at. Default: `2620:0:ccc::2` (OpenDNS) - **scan_interval** (*Optional*): Defines number of seconds for polling interval. Default: `120` seconds. #### {% linkable_title Extended example %} ```yaml # Example configuration.yaml entry sensor: # Own public IPv4 address - platform: dnsip # Resolve IP address of home-assistant.io via Google DNS - platform: dnsip hostname: home-assistant.io resolver: 8.8.8.8 ```
