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 |
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 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.
