Hmm, I don't think 2600:3c00::/64 is dedicated to my host, however
2600:3c00:e000:0137::/64 is. Here is the response I got back from my provider:

To be perfectly clear: 2600:3c00::/64 is shared insofar as other customers have
VMs with IPv6 addresses on the same IPv6 subnet. Your SLAAC-assigned IPv6
address - 2600:3c00::f03c:91ff:feb0:a56f - is a /128 range, which essentially
makes it a single IPv6 address which only your VM can use. The addresses within
your /64 range - 2600:3c00:e000:0137::/64 - can only be used by the VM it's
routed towards.
