#Is there a good base 64 HA encoded IPv6

Be aware of link local addresses and assigned addreses. You may have DHCPv6 active in your network but matter devices could not perse use that and device to only use their locally assigned address and they do neighbour discovery to detect the presence of other devices, as far as I'm aware anyway. @tired sundial probably knows this better than me.
It is interesting though that that one digit was wrong...

Its really bad at "math" questions
Its probably better at giving you some python code that decodes the string for you.

Where did you ping the address from ? From your pc ?
If the device becomes unavailable in HA, it would be great of you could try this ping from within the Matter container
