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 RangeFirst IP AddressLast IP Address
10.2.0.0/1610.2.0.110.2.255.255
172.16.0.0/12172.16.0.1172.31.255.255
192.168.0.0/16192.168.0.1192.168.255.255

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.
