interfaces

go-udap interfaces

What it does

Lists every local network interface that's usable for UDAP discovery. Filter applied: Up + Broadcast + !Loopback + has IPv4 address. The output gives you the NAME values you can pass to --interface.

Output

Fixed-column table:

NAME            INDEX  ADDRESS            BROADCAST
en0             14     192.168.1.118      192.168.1.255
en7             31     192.168.1.226      192.168.1.255

The BROADCAST column is the subnet's directed-broadcast address. It's informational only — UDAP discovery sends to limited broadcast 255.255.255.255 regardless (see How UDAP discovery works for the why).

Exit codes

• 0 — success (even if zero interfaces qualify)
• 2 — OS enumeration error
