"BTW, on IPv6, there's no such thing as broadcast. "
Not sure I like that wording to be honest.. even if technically correct ;) If its the all host/node multicast, and its reserved that can not be used, etc. then how is it not a "broadcast" So you have these 2 addresses
FF02::1 (All host multicast), does this not communicate with every host on the network?? Ie broadcast ;)
These sure seem to be broadcast address to me… Per the rfc https://tools.ietf.org/html/rfc4291#section-2.7.1
If the client has to listen for it.. How is not really broadcast, be it you want to call it broadcast or not ;)
But as mentioned if you do not want to see that noise, there are a few ways to not log it..
