I am trying to query a bittorrent tracker and am using unpack to get the list of IPs from the response. So, something like this:
$ip = unpack("N", $peers);
$ip_add = ($ip[1]>>24) . "." . (($ip[1]&0x00FF0000)>>16) . "." . (($ip[1]&0x0000FF00)>>8) . "." . ($ip[1]&0x000000FF);
But, for some reason, I am getting the following IP addresses when I print $ip_add:
117.254.136.66
121.219.20.250
-43.7.52.163
Does anyone know what could be going wrong?
use long2ip() to transform number back into ip
