# wildcard DNS in localhost development
- install [dnsmasq](http://www.thekelleys.org.uk/dnsmasq/doc.html)
```
$ brew install dnsmasq
   ...
$ cp /usr/local/opt/dnsmasq/dnsmasq.conf.example /usr/local/etc/dnsmasq.conf
```
- edit `/usr/local/etc/dnsmasq.conf`
```
address=/dev/127.0.0.1
```
- start **dnsmasq**
```
$ sudo brew services start dnsmasq
```
- any time we change `dnsmasq.conf` we have to re-start **dnsmasq**:
```
$ sudo launchctl stop homebrew.mxcl.dnsmasq
$ sudo launchctl start homebrew.mxcl.dnsmasq
```
- For OS X to _resolve_ requests from `*.dev` to **localhost** we need to add a _resolver_:
```
$ sudo mkdir /etc/resolver
$ sudo touch /etc/resolver/dev
```
- edit `/etc/resolver/dev`
```
nameserver 127.0.0.1
```
- re-start the computer to enable the _resolver_
