GIAC Security Essentials Certification (GSEC) — Question 24

Which of the following is a private, RFC 1918 compliant IP address that would be assigned to a DHCP scope on a private LAN?

Answer options

• A. 127.0.0.100
• B. 169.254.1.50
• C. 10.254.1.50
• D. 172.35.1.100

Correct answer: C

Explanation

The correct answer is C, 10.254.1.50, as it falls within the private IP address range defined by RFC 1918. Options A and B are not private addresses; A is a loopback address, and B is a link-local address. Option D, while it appears private, is outside the defined ranges of RFC 1918.
