Question
A systems administrator is setting up a server on a LAN that uses an address space that follows the RFC 1918 standard. Which of the following IP addresses should the administrator use to be in compliance with the standard?
- A. 11.251.196.241
- B. 171.245.198.241
- C. 172.16.19.241 Correct
- D. 193.168.145.241
Explanation
RFC 1918 reserves three private ranges: 10.0.0.0/8, 172.16.0.0/12 (172.16.0.0 to 172.31.255.255) and 192.168.0.0/16. Only 172.16.19.241 falls inside one of them. The other addresses resemble private ranges (11 instead of 10, 171 instead of 172, 193 instead of 192) but are public addresses.
