However, Hetzner is complaining that some of our guest MAC addresses are "leaking out". AFAICT, this is happening in neighbour solitications and advertisements, with the link-local addresses.
What do they mean by "leaking out"? How is that happening.

MAC and link local addresses are never seen off the local network, unless something is relaying them.
