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
