Type the iproute2 command, with no interface argument, that displays the IP addresses currently assigned to all network interfaces.

LPIC-1 Exam 102-500, objective 109. Networking fundamentals easy

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.

Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

Case sensitive — Linux is, and grading LS as ls would teach a falsehood.

Why

`ip addr show` (commonly shortened to `ip a`) lists every interface with its state, MAC address and assigned IPv4 and IPv6 addresses. iproute2 accepts unambiguous abbreviations of both objects and subcommands, and `show` is the default subcommand, so `ip addr` alone works. Restrict output with `ip -4 addr` or `ip addr show dev eth0`. The deprecated net-tools equivalent is `ifconfig -a`; plain `ifconfig` without -a omits interfaces that are down, and net-tools shows only one address per interface unless further addresses were added as labelled aliases such as eth0:0.
