CCNA Routing and Switching (legacy) — Question 152

Which RFC was created to alleviate the depletion of IPv4 public addresses?

Answer options

• A. RFC 4193
• B. RFC 1519
• C. RFC 1518
• D. RFC 1918

Correct answer: D

Explanation

RFC 1918 defines private IP address ranges, which help reduce the demand for public IPv4 addresses by allowing organizations to use private addresses internally. The other RFCs listed, such as RFC 4193 (which deals with IPv6 Unique Local Addresses), RFC 1519 (which outlines Classless Inter-Domain Routing), and RFC 1518 (which describes Classless Addressing), do not specifically address the depletion of IPv4 addresses.
