Now, it's necessary to modify <tt>/etc/nsswitch.conf</tt> so that your system will use multicast DNS for hostname lookup. In the example, we use the <tt>mdns_minimal</tt> and <tt>mdns</tt> words, which enable multicast DNS for IPv4 and IPv6. If you only want to enable IPv4-based multicast DNS, which is recommended for IPv4-only networks, use <tt>mdns4_minimal</tt> and <tt>mdns4</tt> instead. This will improve hostname lookup performance.
