192.168.1.x. If you watch in the browser console it’ll show either net::ERR_CONNECTION_REFUSED for a host that’s up or net::ERR_ADDRESS_UNREACHABLE
for a host that doesn’t exist. This is a CORS error which the
javascript on the webpage is not allowed to differentiate by catching.
But one error takes 3 ms to happen and the other takes 3 seconds! [...]kindly refer the following link as follow up :
