Stop all that ip, ifconfig, /dev/net, grep, cut, sed, awk crap!
Use a single binary to do all that for you, reliably, cross-platform.
Sometimes you just need a list of network interface names, or just a single best-guessed network interface name, or just its best-guessed internal IP address. This tool helps you with that.
