Hi folks,
For some reason, every time I create a virtual interface (using
tun), the interface immediately generates an IGMPv3 Join packet for
group 224.0.0.251, which (according to Google) is Multicast DNS.
This packet is generated automatically and consistently. I'm
wondering why this should be the case, and if it can be disabled.
You don't happen to be running "avahi" or one of the other Zeroconf/
Bonjour/Rendezvous/$P2P_BUZZWORD_OF_THE_WEEK local-network-discovery
daemons, do you? Most of those keep an eye out for new network
interfaces and automatically start pushing multicast packets down
them as soon as they appear, which is the most likely explanation for
what you are seeing; as opposed to a kernel issue.
Cheers,
Kyle Moffett
