(http://datatracker.ietf.org/doc/draft-cheshire-dnsext-multicastdns/) 


Enables the simplest 'multicast' dns client by identifying requests for
multicast domain names (eg domain names ending in .local) and submitting the
dns query to 224.0.0.251:5353 

Refer to section 6.1 in above document.

This functionality would enable LWIP applications to resolve .local host
names on LANs without the need to update or manage a DNS server.

Macs, Windows and Linux machines can be easily configurered to respond to
mDNS queries.
