Editor's Note: This file was selected as MATLAB Central Pick of the Week

The Windows code for the ping call is based on isnetavl by Nishant Kumar. To allow drop-in compatibility the name was kept the same.
Because this calls the system command line, the syntax is slightly different between Unix and Windows, as is the response. This function is tested on Windows XP/7/10, Ubuntu 20.04 and MacOS 10.15.
Some organizations block ping from working, in which case an HTML fallback is used (by attempting to load the google.com homepage).
