The `dnsip` sensor will expose an IP address, fetched via DNS resolution, as its value. There are two operational modes:
The `dnsip` sensor will expose an IP address, fetched via DNS resolution, as its value. It provides both IPv4 and IPv6 lookup as separate sensors depending on accessibility to resolvers.
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.
1. When you enable the sensor with the default value, 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.
You may also override the default nameservers that are being used by setting the `resolver` option in the integration to any nameserver you like.
## Configuration
To enable this sensor, add the following lines to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
sensor:
- platform: dnsip
```
{% configuration %}
hostname:
description: The hostname for which to perform the DNS query.
required: false
default: "`myip.opendns.com` (special hostname that resolves to your public IP)"
type: string
name:
description: Name of the sensor.
required: false
default: "`myip` or hostname without dots if specified"
type: string
resolver:
description: The DNS server to target the query at.
required: false
default: "`208.67.222.222` (OpenDNS)"
type: string
ipv6:
description: 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.
required: false
default: false
type: boolean
resolver_ipv6:
description: The IPv6 DNS server to target the query at.
required: false
default: "`2620:0:ccc::2` (OpenDNS)"
type: string
scan_interval:
description: Defines number of seconds for polling interval.
required: false
default: "`120`"
type: integer
{% endconfiguration %}
## 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
name: hass
resolver: 8.8.8.8
```
