RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:
192.168.0.0/16: A private IP range often used in home networks.
10.0.0.0/8: A large private IP range commonly used in enterprise networks.
Invalid Options:
B . 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.
C . 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.
