It is for devices with IP, but to find names that aren't officially
registered in a DNS server. For example if you have a Playstation 3,
or a newer blu-ray player that supports network streaming it will use
DHCP to get an address. But then suppose you install your own DLNA
media server like ps3mediaserver (or have windows 7 home premium which
includes one). Without registering your new server name in DNS, the
device will be able to find the service if it is on the same lan. I
think Macs use it to find printers too.
