In your Startup.cs, make sure you have a method to ConfigureServices, passing in the IServiceCollection, then register IHttpContextAccessor as a singleton as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.AddSingleton();
}

After registering the IHttpContextAccessor in your Startup.cs file, you can inject the IHttpContextAccessor in your controller class and use it like so:

private IHttpContextAccessor _accessor;

public ValuesController(IHttpContextAccessor accessor)
{
    _accessor = accessor;
}

public IEnumerable Get()
{
    var ip = _accessor.HttpContext?.Connection?.RemoteIpAddress?.ToString();
    return new string[] { ip, "value2" };
}
