Explanation
Private IPv4 addresses are designated for use within private networks and do not require global registration or tracking. They are designed for internal use and cannot be routed directly over the public internet.
Common mistakes.
- A. The specific number of available addresses varies greatly by private range; for example, 10.0.0.0/8 offers over 16 million addresses, not just 65,536.
- B. IANA issues public IP addresses and autonomous system numbers, not private IP address ranges for specific organizations; private addresses are locally chosen from predefined ranges.
- D. Private IP addresses are non-routable on the public internet and must be translated (e.g., via NAT) to public IP addresses to traverse the internet, regardless of an outbound ACL.
