System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList
做web程序获取客户端的IP地址用
HttpContext.Current.Request.ServerVariables（"REMOTE_ADDR"]）
你最好可以换台电脑访问网址看获取IP地址状况。
如果你测试访问的时候,使用的是 localhost 进行访问的,那么服务器端获得的也就是127.0.0.1，因为localhost是一个环路地址,特殊的.如果你是通过你的ip地址进行访问的,那么获得的IP地址就会是正确的了. 要通过自己本地的IP进行访问,在控制面板的网络连接里找到本地连接,查看它的属性,并找到"详细信息"按钮,点击后弹出的对话框中IPV4地址就是本地地址.或打开命令行,输入 ipconfig /all 即可找到本地地址.在浏览器中通过这个IP地址访问,就不会是127.0.0.1了.
Dim IPAdress As System.Net.IPAddress
HostName = System.Net.Dns.GetHostName '获得本机的机器名
IPAdress = System.Net.Dns.GetHostByName(HostName).AddressList.GetValue(0) '获得本机的IP
Me.TextBox1.Text = HostName '本机机器名
Me.TextBox2.Text = IPAdress.ToString '本机的IP
我来说说...i试试看行不行。Option Explicit

MsgBox(System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName).AddressList(0).ToString)这是vb2008里面的格式，这是显示自己的IP，不知你是想要获取哪些IP 呢
1.获取当前电脑名：System.Net.Dns.GetHostName()
2.根据电脑名取出全部IP地址：System.Net.Dns.Resolve(电脑名).AddressList
或者 System.Net.Dns.GetHostByName(电脑名).AddressList
3.根据IP地址取出电脑名：System.Net.Dns.Resolve(IP地址).HostName
