# The Great IPv6 Subnetting Committee
**WARNING**: DRAFT SPECIFICATION FOR COSI IPv6 NETWORK
```
Gateway: 2605:6480:c051::1/48
2605:6480:c051:0000:0000:0000:0000:0001
XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX
| |||| |||64 . . User IP addresses
| |||| ||60
| |||| |56
| |||| 52
| |||48 . . . . COSI Subnet Size
| ||44
| |40
| 36
32 . . . . . . . Clarkson’s Subnet Size
```
## 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
# Allocations!

2605:6480:c051::1/128 | OIT Gateway (the only one)
2605:6480:c051:0xxx::1/52 | Server Network (each server gets a /64)
2605:6480:c051:1xxx::1/52 | DHCP Network (each user gets a /64)
2605:6480:c051:2xxx::1/52 | Static User Networks (users get their own /64’s)
2605:6480:c051:3xxx::1/52 | Shenanigans that can get IP’s blocked
... (4-b) | Reserved for future use
2605:6480:c051:cxxx::1/52 | Random “C” Stuff (COSI, CS, Computer, etc.)
2605:6480:c051:dxxx::1/52 | VPN/Remote Locations

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