# The Great IPv6 Subnetting Committee

**WARNING**: DRAFT SPECIFICATION FOR COSI IPv6 NETWORK

```
Gateway: 2605:6480:c051::1/48

## 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.
