What do you mean by this? Are you taking about mDNS still referencing the withdrawn prefix?

If two hosts have both mutually accessible ULA and GUA addresses, they will prefer _GUAs_ to talk to each other. So the connection will be susceptible to the prefix withdrawal if the upstream goes down (BTW, IPv6 did nothing sane for multihoming either).

That too.

Oh, interesting. My machines have not had good mDNS support, so I have been hardcoding ULAs for LAN-only traffic.
