I'm looking for a function that will give me my real IP, not my local IP. the function i currently have, returns the ip in network and sharing center which is 192.168.2.100 But if I go to whatismyip, then it gives my real IP.How could I get this using VB.NET?

In a WinForm application, if you want to get the IP address of the machine the code is running on (for instance, to log in the database what the IP address is when a user deletes a record), I would use this
Dim xEntry As System.Net.IPHostEntry = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName)
Dim ipAddr As Net.IPAddress() = xEntry.AddressList
blIP.Text = ipAddr(0).ToString()
While the code works, and it returns the correct IP address (for example: 140.139.138.137), Visual Studio doesn't like that code, and tells you that GetHostByName is obsolete, and needs to be replaced with GetHostEntry.
But if I do that, then I get back something that does not look like an IP address:
fe80::28ba:e091:1056:949f%11
So my question is, if I'm not supposed to use GetHostByName because it's been replaced by GetHostEntry, how come GetHostEntry doesn't give me the IP address?
Are there any IP Address filters or masks available in Windows Forms as per following screenshot? A backslash shouldn't be allowed or it should be filtered somehow.

View 1 RepliesI'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

View 1 RepliesI need to generate 'real' random numbers from 0 to 500 (e.g. 247.214, 477.125, 1.247, 54.078, 147.001 ......etc). I am using this method:
Dim Myrand As New Random
Dim Res As Double
For i = 1 To 10
Res = Math.Round(Myrand.NextDouble, 3)
Next
This method gives numbers between 0 and 1. if I use: Res = Myrand.Next(0,500), then this gives Integer numbers.
The questions is: Is this possible with (Dim Myrand As New Random) or I have to try another way (e.g. Rnd() ) for doing this?
