How to check IP addresses and network interfaces in Linux

List IP addresses, interfaces, and link state with ip addr and ip link, including a compact one-line brief.

See the machine network interfaces and their IP addresses. ip addr is the full view; ip -br addr is a compact one-line-per-interface brief. The old ifconfig is deprecated.

# All interfaces and IP addresses
ip addr

# Brief, one line per interface
ip -br addr

# Link state (up/down, MAC, MTU)
ip link

# One interface only
ip addr show <if>
