01Command

Command

$ ipconfig getsummary en0 | head -30

02What it does

While `ipconfig getifaddr en0` shows just the IP, getsummary dumps everything the DHCP client knows: assigned addresses, router, lease times and DNS — useful when a Mac connects but you suspect a half-broken lease. It also includes the SSID and channel for Wi-Fi interfaces. Pipe through `head` or `grep` because the full output is long.
