====== Multicast DNS ====== * [[Avahi]] * [[dnsmasq]] * [[OS X]] Multicast DNS provides hostname resolution as well as advertises services to local computers. It is only available on a LAN, and will not work over VPN. === OS X === OS X relies heavily on multicast DNS for name resolution, and will often prefer mDNS over a local DNS server for primary lookups. Using ''host'' will use the DNS server to do a lookup. Using ''ping'' will use mDNS to do the lookup.
