Get Visitor's IP Address

Manoj Bisht · March 31st, 2009, 08:24 AM

Hello Friend,
I want to get the Visitor's IP Address. For it, i'm using the following code

string hostName = Dns.GetHostName();
IPHostEntry hostEntry = Dns.GetHostEntry(hostName);
IPAddress[] ipAddress = hostEntry.AddressList;
string name = null;
for(int i=0;i<ipAddress.Length;i++)
{
name = name + ipAddress[i].ToString()+" ";
}
Response.Write(name.ToString());

This code is showing the correct IPAddress of the local computer on localhost but as i upload this code over my server it gives me the following IPAddress not of my computer

66.63.181.68
66.63.181.93
216.45.55.186

Secondly, i use the following code

string hostName1 = Request.UserHostName.ToString();
Response.Write(hostName1.ToString());
But this is giving the IPAddress of the Main computer, I mean there are four computers, sharing the internet connection from my PC and when i visit the page from any of those computers it always give me the IP of my PC

Maybe I will not be very clear with why are you seeing this, but you could read about how IP works.

If your computer is giving internet to the rest, then for example, the only computer that has an IP address is the one that is really connecting to the internet. But maybe you are seeing a different address, because if you are in a intranet is not the same address like when you connect to outside. My pc has an IP inside my office, but when I go outside it has another IP. The problem is not your code, the problem is your logic. ;)
