CompTIA Network+ (N10-007) — Question 400

A user checks an IP address using an external website. The address is different than the one the user sees when opening a command prompt and typing in ipconfig/all. The user does not understand why the two tools show different IP addresses. This is BEST explained by the interworking of:

Answer options

• A. network devices
• B. packet flow
• C. public/private networks
• D. traffic-routing protocols

Correct answer: C

Explanation

The correct answer is C, as the difference arises from the distinction between public and private IP addresses. The IP address shown in the command prompt is likely a private address assigned by a router, while the external website displays the public IP address used for internet communication. Options A, B, and D do not directly address this discrepancy.
