@stux @mur2501 And even if they did see an IPv6 address coming from that machine that shouldn't, shouldn't that be blocked by firewalls/routing rules and they just warn me of a potential problem, instead of shutting down IPv6 entirely.
I've been running a TCP dump on my host for the IP they mention and nothing has come up for over an hour.
I really need to look into building a full backup standby.
@mur2501 @djsumdog Hmm.. That is weird..!
How can you even "use" an IPv6 when not assigned?
