// title: IP detector
// author: prko
// description:
// This code outputs an array consisting of local IPs (or an array with one local IP if there is only one) except “127.0.0.1”.
// 
// It successfully detects multiple IPv4 addresses as well as one IPv4 address under macOS 12.2.1 and Windows 11. However, under Ubuntu 20.04.3, which ran over Parallels Desktop, I strangely could not assign IPv4 to the second network card. Thus, I confirmed only the output of an array with one IP, but I hope it also could output multiple IPs.

// The following strings are to avoid listing network bridges which seem to be created by Parallels Desktop:
// | grep -Fv "inet 10."
