Objective 1.7N10-009

1.7 Given 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.

Networking ConceptsEasy

Which of the following address ranges is designated in RFC 1918 as private address space for internal enterprise use?

Correct.

The concept

RFC 1918 sets aside specific IPv4 blocks for private, non-globally-routable use inside an enterprise.

Why this answer

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.

  • Correct: this block is explicitly one of the RFC 1918 private ranges.
  • BThis is the APIPA/link-local range, not an RFC 1918 private range.
  • CThis is the loopback range reserved for a host to address itself, not a private allocation range.
  • DThis is the multicast range (Class D), unrelated to private addressing.

Now you: objective 1.7 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 2

Networking ConceptsModerate

A company's warehouse scanners only ever talk to a local server and never require access outside the building's network. Per RFC 1918, which address range fits this 'private' host category?

Sample question 2 of 2

Networking ConceptsHard

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?
