In trying to track down another problem I have noticed that there is a huge amount of mdns generated by my machine. This is on the order of 1400 packets a second, that is kind of much I assume. I have included the details on one of these packets below. My machine is on a private net with IP 192.168.172.13 and the other machine (steinbit) is on the other side of a nat with a internet visible IP 204.72.xx.xx (to protect the innocent). If it matters my machine is a laptop that regularly moves between two different private networks natted to the internet (work and home). I would appreciate any idea about what is going on an what I can do to stop it.
