c# - Getting 127.0.0.1 when using HttpContext.Features.Get<IHttpConnectionFeature>()?.RemoteIpAddress -

i using asp.net core mvc. trying ip address using below code.

var ipaddress = httpcontext.features.get<ihttpconnectionfeature>()?.remoteipaddress?.tostring(); 

its returning ::1 means 127.0.0.1 on local machine fine. have hosted on azure cloud testing using testing azure account , still giving me 127.0.0.1.

what doing wrong?

this happen because of reverse proxy. asp.net core iis send request kestrel server processing , mvc 6 ( asp.net core) receive request after issue come header information not forwarded.

following thing solve problem.

in startup.cs file.

public void configure(iapplicationbuilder app, ihostingenvironment env, iloggerfactory loggerfactory)     {       loggerfactory.addconsole(configuration.getsection("logging"));       loggerfactory.adddebug();       app.useforwardedheaders(new forwardedheadersoptions() { forwardedheaders = microsoft.aspnetcore.httpoverrides.forwardedheaders.all }); // must first line. ( before other middleware configured)       // other code     } 

update 1 1. don't use service.configure , app.useforwardedheaders together. ( have tried use both option , ended 127.0.0.1). 2. have use app.useforwardedheaders , works fine.

my minimal configuration file. ( startup.cs)

public class startup {     public void configureservices(iservicecollection services)     {          services.addmvc();         //services.configure<forwardedheadersoptions>(option => { option.forwardedheaders = microsoft.aspnetcore.httpoverrides.forwardedheaders.all; });  // option should not used. gives me 127.0.0.1 if have used option.     }      public void configure(iapplicationbuilder app, ihostingenvironment env, iloggerfactory loggerfactory)     {         loggerfactory.addconsole(loglevel.debug);         app.useforwardedheaders(new forwardedheadersoptions() { forwardedheaders = microsoft.aspnetcore.httpoverrides.forwardedheaders.all });         app.usestaticfiles();          if (env.isdevelopment())         {             app.usedeveloperexceptionpage();         }          app.usemvc();     } } 

update 2

later tried service.configure , works. in case have use service.configure , avoid using app.useforwardedheaders.

in case startup.cs file this.

public class startup {     public void configureservices(iservicecollection services)     {          services.addmvc();         services.configure<forwardedheadersoptions>(option => { option.forwardedheaders = microsoft.aspnetcore.httpoverrides.forwardedheaders.xforward‌​edfor; });       }      public void configure(iapplicationbuilder app, ihostingenvironment env, iloggerfactory loggerfactory)     {         loggerfactory.addconsole(loglevel.debug);         //app.useforwardedheaders(new forwardedheadersoptions() { forwardedheaders = microsoft.aspnetcore.httpoverrides.forwardedheaders.all });         app.usestaticfiles();          if (env.isdevelopment())         {             app.usedeveloperexceptionpage();         }          app.usemvc();     } }
