DNS IP Sensor


The dnsip sensor will expose an IP address, fetched via DNS resolution, as its value. There are two operational modes:

  1. When you enable the sensor with minimal configuration, it will query the OpenDNS 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.

Configuration

To enable this sensor, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: dnsip

Configuration variables:

  • hostname (Optional): The hostname for which to perform the DNS query. Defaults to myip.opendns.com (special hostname that resolves to your public IP).
  • name (Optional): Name of the sensor. Defaults to myip or hostname without dots if specified.
  • resolver (Optional): The DNS server to target the query at. Defaults to 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. Defaults to 2620:0:ccc::2 (OpenDNS).
  • scan_interval (Optional): Defines number of seconds for polling interval. Defaults to 120 seconds.

Extended example

# 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
    name: hass
    resolver: 8.8.8.8
