/64

That's not an address, that's a whole fucking subnet consisting of 2^64 different addresses. ☝️🤓

It is a single address with an associated subnet mask, indicating what subnet the address is in.

The subnet would be 3fff:a1:1ab:bc67::/64, for the top one.

I'll see you in court.

Maybe but I always have to enter /24 after setting a VM's manual IP for it to be valid

[–] Kazumara@discuss.tchncs.de 8 points 1 day ago

That would depend on the network environment. If your VM is on a /28 subnet and you set /24 it won't be valid
