Objective 1.7
N10-009Given a scenario, use appropriate IPv4 network addressing.
Objective 1.7 sits in Networking Concepts, which carries 23% of the Network+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Which of the following address ranges is designated in RFC 1918 as private address space for internal enterprise use?
Correct.
Checked against datatracker.ietf.org, August 2026Concept
RFC 1918 sets aside specific IPv4 blocks for private, non-globally-routable use inside an enterprise.
Why A
10.0.0.0/8 is one of the three blocks (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) that RFC 1918 reserves for private internets.
Source
RFC 1918: Address Allocation for Private Internets, checked August 202610.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)…
Now you: objective 1.7 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A company's warehouse scanners only ever talk to a local server and never require access outside the building's network. Which private address range fits this host category?
Sample question 2 of 3
In the early 1990s, engineers identified both Class B address exhaustion and rapid growth of global routing tables as related problems. Which strategy resolved both concerns at once?
Sample question 3 of 3
A technician watches a laptop self-configure an IPv4 link-local address after DHCP produces no reply. Which address could the host have selected?
