VPCs

A column exists inside a single VPC. The second octet must be unique to the VPC.

Datacenter	Prod Second Octet	Dev Second Octet
us-west-2	0	100
us-west-1	4	104
us-east-1	8	108
eu-west-1	12	112
eu-central-1	16	116
ap-southeast-1	20	120
ap-southeast-2	24	124

Subnets

A column exists inside a single VPC. The second octet must be unique to the column for a deployment. The following table shows the production VPC in us-west-2.

	Cidr	Minimum	Maximum	Broadcast	Hosts
VPC	10.0.0.0/16	10.0.0.1	10.0.255.254	10.0.255.255	65534
1PuS	10.0.0.0/18	10.0.0.1	10.0.63.254	10.0.63.255	16382
2PuS	10.0.64.0/18	10.0.64.1	10.0.127.254	10.0.127.255	16382
1PrS	10.0.128.0/19	10.0.128.1	10.0.159.254	10.0.159.255	8190

VPNs

VPNs are also by second octet and there is one per column. To determine the second octet for a column, add 1 to the VPC second octet. For example, the VPN second octet for us-west-2 is 1.
