Manage CIDR Ranges
Create, view, edit and, delete CIDR Ranges and CIDR Range Exclusions
All Stax VPCs reside within a CIDR Range. A CIDR Range is the overarching object within a Stax Networking Hub that contains VPCs and Exclusions. The configured CIDR Range must be contained within an RFC1918-compliant private address space. You should confirm your CIDR ranges with your networking team before configuring them in a Stax Networking Hub. Some examples of supported CIDR ranges are below.
| CIDR Range | First IP Address | Last IP Address |
|---|---|---|
| 10.2.0.0/16 | 10.2.0.1 | 10.2.255.255 |
| 172.16.0.0/12 | 172.16.0.1 | 172.31.255.255 |
| 192.168.0.0/16 | 192.168.0.1 | 192.168.255.255 |
The largest supported size for a Stax CIDR Range is /8, while the smallest is /23.
CIDR Ranges support Exclusions to exempt certain portions of CIDR ranges that must be excluded for past/future use.
