I'm using dns to ip script but it always give me the old ip ( maybe it using cache or something like that ) how i can get the new dns ip ?

            var ips = System.Net.Dns.GetHostEntry("mann.chickenkiller.com").AddressList;
        foreach (var ip in ips)
        {
            MessageBox.Show(ip.ToString());
        }

ipconfig /flushdns not working – Khalil Hamdi Sep 09 '16 at 11:38
well, what does your system's command line tell you if you request the resolved dns ( eg by ping ) ? is that Ip adress correct? I stronlgy believe, that your computer, router, gateway whatever, still has it cached – Najzero Sep 09 '16 at 11:39

hm, try `tracert` on your hostname - maybe one of the nodes on the route notices the changed DNS/IP combination – Najzero Sep 09 '16 at 11:47
