It's a odd size but more for being too stingy - normally in these kinds of setups you get something like a /48 or /56 for routing which lets you still have some bits for routing and then you can hang normal /64 subnets at the end of your routes.

Operating systems don't support non-64 prefixes very well and v6 wasn't designed to work like that.

Then how do routers work? Docker containers? VMs running on a machine with some part of a /64?
