Validate IP address

[MrPike]

I want to validate the IP address entered into a textbox is a valid IPV4 format. ie 192.168.1.1.  Does anyone have a code sample that works?  I have googled this but my limited VB knowledge is quickly exceeded and I cant get anything to work, thanks.

The trick to finding Google answers is to precede your search with ".NET", so I would search like this:

".net ip address parse"

But here is the answer you are looking for:

Code: [Select]

Dim IPAddress as System.Net.IPAddress
If NOT System.Net.IPAddress.TryParse(TextBox1.Text,IPAddress) then
    MsgBox "Invalid Address"
End If
