Today I see some interesting things under the TCP protocol. They're marked as [TCP Retransmission]. Source is 2600:1000:b150:3c0:redacted, destination is 2001:470:1f06:redacted.
To answer your question from yesterday, the ICMPv6 stuff that I see is coming from a couple of Amcrest cameras, and they say "Router Solicitation from xx:xx:xx:mac address".
