IP detector

22 Oct'22 06:09 in IP detectorIP detector

This code outputs an array consisting of local IPs (or an array with one local IP if there is only one) except “”. 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. related post:
