    You cannot. Application startup happens only once, and long before any request has been received. In other words, there's no request to get information from. – Chris Pratt Apr 05 '19 at 18:21

    By “host” do you mean the domain name of the web service? Or the name of the physical server? – John Wu Apr 05 '19 at 21:20

  • @ChrisPratt you are correct. We can't use this in startup. I figure out another way full fill my requirement. Thanks a lot for saving my time. – Chamara Nillushan Apr 06 '19 at 09:41

try this:

    public static string GetAddressIP()
    {
        return Dns.GetHostAddresses(Dns.GetHostName())
            .FirstOrDefault(ha => ha.AddressFamily == AddressFamily.InterNetwork)
            .ToString();
    }
