NAME

mdns - Multicast DNS
SYNOPSIS
mdns [ifn1 [ifn2]]
mdnsx [ifn] [on | off]

 

DESCRIPTION
Command mdns sets the interface numbers ifn1 and ifn2 between which multicast DNS packets are to be propagated. This feature allows hosts on one network to discover hosts on another network.

Command mdnsx sets multicast reply on or off for the specified interface. This allows hosts to resolve special names such as nat32, nat32.local, nat32.box, nat32.win and nat32.vpn.

NOTES
Various Apple® devices use multicast DNS to resolve names and discover services on a network. NAT32 can propagate such packets from one interface to another, thereby allowing devices on one network to discover (and use) services available on another network.

In all cases, NAT32 uses information gleaned from mDNS packets to populate entries in its Network Neighborhood Table.
