Pubface is a small Node.js utility that discovers the public‑facing network interfaces on the current machine, returning details such as local address, external IP, reverse‑DNS name, IP family and whether the interface is the system default. It can be used as a library (`resolvePublicInterfaces`) or installed as a command‑line tool for developers, sysadmins, or scripts that need to programmatically identify outward‑visible IPs.
