How to set up a DNS server on MAC OS X?

Question

Apache HTTP Server

I use MAMP local assembly of the web server on MAC OS X.
In order not to register a new host, Httpd.conf used vhost_alias and configured automatic addition of new virtual hosts to Apache in this way:

UseCanonicalName Off
ServerName loc
ServerAlias ​​*.loc
VirtualDocumentRoot /Volumes/HDD/Sites/%1

But this only half automates the addition of the host, I'm still forced to add new addresses to the hosts file. As far as I understand, not to do this every time. I need to start a local DNS server and configure it to redirect me automatically (/Sites/mysite -> mysite.loc). Hence the question of how to run and configure this dns.
