This reminds me of AWS's solution for everybody selecting the first 2 availability zones which made the 3rd one to be under-used, and the first 2 over-used. So they introduced AZ IDs https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#az-ids https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-re... which create a per-account randomized mapping of region to actual availability zone. And it's logical that we do so. We clean up, we put things in corners, we sort things. So I suppose many people set static IPv6 addresses at the bottom of their /64?
