Check if the internet works – Python

Just check a google server

1 2 3 4 5 6 7

importurllib2 definternet_on():     try:         response=urllib2.urlopen(‘http://74.125.228.100’,timeout=1)         returnTrue     excepturllib2.URLError aserr:pass     returnFalse

74.125.228.100 is one of the IP-addresses for google.com. Change http://74.125.228.100 to whatever site can be expected to respond quickly.
Using a numerical IP-address avoids a DNS lookup, which may block the urllib2.urlopen call for more than a second.

Thanks to @rzetterberg for pointing this out.

By specifying the timeout=1 parameter, the call to urlopen will not take much longer than 1 second even if the internet is not “on”.

Good Luck
