Probably related to #63 but I need more input. please set the environment variable DEBUG to mdns:input and run again. DEBUG=mdns:inbound node <your code file>

This will output some messages starting with mdns:inbound and then the packet in bytes. Add those lines to this issue.

Same issue was discussed in https://github.com/agnat/node_mdns/issues/138. And there they concluded that it was...

Okay, I saw that the service is actually violating the specification (page 19 of http://www.ietf.org/rfc/rfc6763.txt).

I have seen a similar mobdev package in the data for #27 (not related issue though) but there the full address is 46c20544._sub._apple-mobdev2._tcp.local and in this issue it's _sub._apple-mobdev2._tcp.local.

It's missing something in the name it seems. I'll have to think about this one.
