Not detecting responses from IPv6 addresses #44

Closed AlCalzone closed 6 years ago

AlCalzone commented 6 years ago

I'm trying to detect an IKEA TRADFRI gateway using this library without any success. When inspecting the traffic with Wireshark, I do see a response from that gateway but it seems to be the only one using IPv6 addresses. As a result it doesn't show up in the detected services. Here's the dissected packet from Wireshark:

Frame 5023: 769 bytes on wire (6152 bits), 769 bytes captured (6152 bits) on interface 0

Is there any way to make bonjour listen to the IPv6 addresses too?

Closing this, as there doesn't seem to be any activity here. In case any one stubles across this, mdns-server is working flawlessly in mixed networks.
