C# || How To Get The Computer & User Client IP Address Using C#

Print Friendly, PDF & Email

The following is a module with functions which demonstrates how to get the computers and user client request IPv4 IP address using C#.

The function demonstrated on this page returns the IPv4 address of the calling user. When under a web environment, it returns the clients System.Web.HttpContext.Current.Request IP address, otherwise it returns the IP address of the local machine (i.e: server) if there is no request.

The following function uses System.Web to determine the IP address of the client.

Note: To use the function in this module, make sure you have a reference to ‘System.Web‘ in your project.

One way to do this is, in your Solution Explorer (where all the files are shown with your project), right click the ‘References‘ folder, click ‘Add Reference‘, then type ‘System.Web‘ in the search box, and add the reference titled System.Web in the results Tab.
