How do I capture the actual Public IP/IP of the user accessing the application? The IP address of the computer I can capture normally, but I want to know the public IP address of this client.

This is a variable accessible in any Action:
Request.UserHostAddress;
Or else:
Request.ServerVariables["REMOTE_ADDR"]

I get it like this:
public static string GetPublicIP()
{
string url = "http://checkip.dyndns.org";
System.Net.WebRequest req = System.Net.WebRequest.Create(url);
System.Net.WebResponse resp = req.GetResponse();
System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream());
string response = sr.ReadToEnd().Trim();
string[] a = response.Split(':');
string a2 = a[1].Substring(1);
string[] a3 = a2.Split('<');
string a4 = a3[0];
return a4;
}

add the using
using System.Net;

string host = Dns.GetHostName();
string ip = Dns.GetHostAddresses(host)[2].ToString();

This code returns the machine’s local IP and not its internet IP. So much so that if you access http://www.meuip.com.br and create an application with the informed code, you will see that the two different ip’s.

@Zackmorgan But the goal is to get the IP of who is accessing my application. Not my public IP.

This application IP is of no use to me in a judicial audit process. Because you see, my machine can have IP 10.10.1.20 in my network. But also, in another network of a neighbor, he may also have the same IP address. Then, with the Real IP, if necessary, I contact the provider, he tells me the necessary information and consequently, if you take the necessary measures. In my application I already capture the IP of the computer, which is totally "useless" for me.

@Zackmorgan is not the IP of the computer. It is the IP remote of client, in this case, who is accessing your application. The documentation makes this clear.

I did the following, I do it on the client’s side. Via javascript, because whoever requests javascript to some service that provides the real IP is the client. Because I need this type of IP. That way, I have a variable that sends this IP to my controller, and I also capture this remote IP. If it’s the best way I haven’t, but it worked, it did.

I find it a little too laborious this way, but I admit it works.
