ANSWER:
To get the client IP address in asp.net core, you need to get it from of request header because request header contains all information of the user including IP address.
You need to create a short function as below:
public static string GetClientIPAddress(HttpContext context) { string ip = string.Empty; if (!string.IsNullOrEmpty(context.Request.Headers["X-Forwarded-For"])) { ip = context.Request.Headers["X-Forwarded-For"]; } else { ip = context.Request.HttpContext.Features.Get<IHttpConnectionFeature>().RemoteIpAddress.ToString(); } return ip; }GetClientIPAddress(context):This is a common function you can put it to some class statics to can reusable. This function will receipt into a HttpContext param.From your action of some controller you want to get client Ip, you can code as below:
string clientIp = Utils.GetClientIPAddress(HttpContext); if (!string.IsNullOrEmpty(clientIp) && clientIp != "::1") { // To do something here }I hope short information is helpful to you.
