Allocation Space

2 Bytes of reasonably addressable space (from the top of the allocated subnet to the /64's)

Objectives:

Subnet for servers
Subnet for a security network
Subnet for DHCP
Subnet for Static IP’s for users (/64 per person (not device)?)
Reserved space for future use?

Number of /64’s contained

/48: 65,536
/52: 4,096
/56: 256
/60: 16
/64: 1

Terms:

Allocations: Logical groupings of devices

Technically, containers and VM's are in a /57? if we cared. Big enough? 2048 addresses.
