Which statement about RFC 1918 private addresses is true?

• A. They are routable on the public Internet
• B. They are not routable on the public Internet
• C. They must be unique globally
• D. They are reserved for documentation only

Answer: (B)

RFC 1918 private addresses are meant for internal networks and are not routable on the public Internet. These ranges can be used inside a private network and can be duplicated in different organizations without causing global conflicts, because they are not reachable from outside the local network. To reach the Internet from these addresses, devices typically use network address translation (NAT) to map private addresses to a public one. The idea that private addresses are reserved solely for documentation is incorrect; documentation-addresses exist in a different context, not tied to RFC 1918.
