Hass.io Core Add-on: Dnsmasq

A simple DNS server.

About

Setup and manage a Dnsmasq DNS server. This allows you to manipulate DNS requests. For example, you can have your Home Assistant domain resolve with an internal address inside your network.

Installation

The installation of this add-on is straightforward and easy to do.

1. Navigate in your Home Assistant frontend to Hass.io -> Add-on Store.
2. Find the "Dnsmasq" add-on and click it.
3. Click on the "INSTALL" button.

How to use

The add-on has a couple of options available. For more detailed instructions see below. The basic thing to get the add-on running would be:

1. Start the add-on.

Configuration

The Dnsmasq add-on can be tweaked to your likings. This section describes each of the add-on configuration options.

Example add-on configuration:

{
  "defaults": ["8.8.8.8", "8.8.4.4"],
  "forwards": [
    {"domain": "mystuff.local", "server": "192.168.1.40"}
  ],
  "hosts": [
    {"host": "home.mydomain.io", "ip": "192.168.1.10"}
  ]
}

Option: defaults (required)

The defaults are upstream DNS servers, where DNS requests that can't be handled locally, are forwarded to. By default it is configured to have Google's public DNS servers: `"8.8.8.8", "8.8.4.4".

Option: forwards (optional)

This option allows you to list domain that are forwarded to a different (not the default) upstream DNS server.

Option: forwards -> domain

The domain to forward to a different upstream DNS server.

Option: forwards -> server

The DNS server to forward the request for this domain to.

Option: hosts (optional)

This option allows you to provide local static answer for your DNS server.

This is helpful for making addresses resolve on your internal network and even override external domains to be answered with a local address.

For example, one could set myuser.duckdns.org to resolve directly to a internal IP address, e.g., 192.168.1.10. While outsite of this network, it would resolve normally.

This options allows you to create a so called: Split DNS.

Option: hosts -> host

The hostname or domainname to resolve locally.

Option: hosts -> ip

The IP address Dnsmasq should respond with in its DNS answer.
