 \term{Multicast DNS} (mDNS)~\cite{rfc6762} describes an extension to the Domain
 Name System that allows DNS resource records to be distributed on multiple hosts
 in a network, therefore avoiding central authorities and enabling every host to

 Software that supports mDNS listens on the reserved
 link-local multicast address \code{224.0.0.251} (for IPv4 queries) or
-\code{FF02::FB} (for IPv6 queries) on UDP port 5353 for incoming queries.

 Queries sent to those multicast address and port are standard DNS queries.
 If a host receives a query and knows about the queried resource, it responds to the
 querying host with a standard DNS response. The querying host can then simply

 Another feature of Multicast DNS is the reduction of traffic through
