使用方法：

在form中调用GetSub就行了。

List1.AddItem ("公网IP:" GetSub + "..")。

VB.NET2010 怎么获取IP

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

VB点虐 2015 如何获取外网IP并保存到软件目录下的IP.txt文件

Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted

Dim str As String

str = Me.WebBrowser1.Document.Body.InnerHtml

Dim a As Integer = 0

Dim b As Integer = 0

a = InStr(str, "[")

b = InStr(str, "]")

TextBox1.Text = Mid(str, a + 1, b - a - 1)

End Sub

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Me.WebBrowser1.Navigate("

)

End Sub

End Class

网页上显示的有点问题，form1_load 中代码是：Me.WebBrowser1.Navigate("")

原理：访问查IP网页后，获取网页上显示的本机外网ip地址
