You may define up to 5 total Networks in your custom private addressing account. Network IP ranges may be unique or may overlap with each other. For most customers, management is simplest if you define a single Network. If you define more, we recommend non-overlapping Networks unless your application requires otherwise.

Navigate to Network -> Private Networks, then click the Add Network link. Specify the Network’s RFC 1918-valid IPv4 private address root in CIDR notation. For example, “10.32.0.0/16” creates a CPA Network starting at 10.32.0.0 with 16 bits (the “10.32”) reserved for the non-host portion of the address. Give your Network a meaningful name and, optionally, a short descriptive note. When finished, click the “Add” button.
