使用方法：调用GetIP 返回值即为公网IP

Private Sub Command1_Click()

Dim aa As String

Dim strLocalIP As String

Dim winIP As Object

aa = aa & ”本机电脑名称:“ & Environ(”computername“)& vbCrLfaa = aa & ”本机用户名称:“ & Environ(”username“)& vbCrLfSet winIP = CreateObject(”MSWinsock.Winsock“)

strLocalIP = winIP.localip

MsgBox aa & ”本机IP:" & strLocalIP

End Sub

第二篇：PHP 获取客户端真实IP地址多种方法小结

PHP 获取客户端真实IP地址多种方法小结

经过复杂的判断与算是的获取IP地址函数 复制代码 代码如下: function getIP(){

if(getenv('HTTP_CLIENT_IP')){ $ip = getenv('HTTP_CLIENT_IP');}

elseif(getenv('HTTP_X_FORWARDED_FOR')){ $ip = getenv('HTTP_X_FORWARDED_FOR');}

elseif(getenv('HTTP_X_FORWARDED')){ $ip = getenv('HTTP_X_FORWARDED');}

elseif(getenv('HTTP_FORWARDED_FOR')){ $ip = getenv('HTTP_FORWARDED_FOR');} elseif(getenv('HTTP_FORWARDED')){ $ip = getenv('HTTP_FORWARDED');} else {

$ip = $_SERVER['REMOTE_ADDR'];} return $ip;

} 最简单获取ip地址代码一句实例

复制代码 代码如下: $reIP=$_SERVER[“REMOTE_ADDR”];echo $reIP;php获取ip的算法

复制代码 代码如下: if(getenv('HTTP_CLIENT_IP')){ $onlineip = getenv('HTTP_CLIENT_IP');

} elseif(getenv('HTTP_X_FORWARDED_FOR')){ $onlineip = getenv('HTTP_X_FORWARDED_FOR');} elseif(getenv('REMOTE_ADDR')){ $onlineip = getenv('REMOTE_ADDR');} else {

$onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];}

echo $onlineip;可以分出内网与外网站ip地址获取程序

复制代码 代码如下: function getip_out(){ $ip=false;

if(!empty($_SERVER[“HTTP_CLIENT_IP”])){ $ip = $_SERVER[“HTTP_CLIENT_IP”];} if(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){ $ips教程 = explode(“, ”, $_SERVER['HTTP_X_FORWARDED_FOR']);if($ip){ array_unshift($ips, $ip);$ip = FALSE;} for($i = 0;$i < count($ips);$i++){

if(!eregi(“^(10│172.16│192.168).”, $ips[$i])){ $ip = $ips[$i];break;} } }

return($ip ? $ip : $_SERVER['REMOTE_ADDR']);}

echo getip_out();php获取ip的算法，用了？号表达式来处理

复制代码 代码如下: $user_IP =($_SERVER[“HTTP_VIA”])? $_SERVER[“HTTP_X_FORWARDED_FOR”] : $_SERVER[“REMOTE_ADDR”];$user_IP =($user_IP)? $user_IP : $_SERVER[“REMOTE_ADDR”];
