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:

```yaml
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 outside 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.
