CompTIA A+ 220-701/702 Practice Exam

Answer - B - The private IP address ranges are defined in three sets: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. Hence, the only private network range in the set above is the 10.0.0.0 to 10.255.255.255 range.

Key Takeaway: Private IP addresses are private if they are not allocated to a specific organization. Private IP address spaces were originally defined in efforts to delay IPv4 address exhaustion. These addresses are common in home and office LANs, as globally-routable addresses are scarce and expensive to obtain.
