Getting your
visitor IP address is very common requirement for Web Development and there is more
confusion about to get IP in best ways.
It will supports all version of .NET Framework (4.8 4.7.2 4.7.1 4.7 4.6.2 4.6.1 4.6 4.5.2 4.5.1 4.5 4.0 3.5 3.0 2.0
1.1)
The Easiest and best way to do the below code:-
string
clientIPAddress = Request.UserHostAddress;
When you are
testing at your local machine, you will be getting clientIPAddress = 127.0.0.1.
After deploying your page on some server or IP, you will be getting correct
client IP addresses.
string
cIPAddress = ((clientIPAddress == "::1") || (clientIPAddress == "127.0.0.1")) ? "149.202.91.218" : clientIPAddress;
Note:
- If the server is behind a load balancer, then you may need to use Request.ServerVariables["HTTP_X_FORWARDED_FOR"]
.
In this case proceed with caution and take only the address that the load
balancer has added.
public string
GetIPAddress()
{
string
IPAddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if
(IPAddress == null)
IPAddress =
HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
return
IPAddress;
}
Sometimes if NAT is enabled on web
server there are cases when it always picks local IP Address no matter what
method you use.
