How to get clients computer name using asp.net mvc?

No you can't, unless the client sends such info when making HTTP requests. By "client", I'm referring to any - some app, browser, etc.

You can inspect your own browser request flow using standard browser dev tools and see exactly what info your browser is sending. It will not have your machine name (unless something in your machine is and that would likely be a problem).

That said, HTTP Header data is what you have aside from standard network info such as IP address (which also isn't guaranteed to be the client's IP address - it could be the client's network address). The closest you can get to is hostname if it exists, and even then, just like IP address, is not guaranteed to be machine name.

A possible exception would be in an internal network (LAN).

How do I get the local machine name in C#?

It works unless a machine name has more than 15 characters.

How to get client's computer name

Two things to consider:

1. Take into account that HttpContext.Current.Request.ServerVariables.Item("REMOTE_HOST") will return the name of the host making the request, not the address.
2. Try doing System.Net.Dns.GetHostByAddress(Request.ServerVariables.Item("REMOTE_HOST")).HostName instead.

You can find a list of the Server Variables at Microsoft's MSDN website.

Hope that helps,

How to get the computer name using the IP Address

Here is how to obtain it on a different machine. This will also give you the IPv4 version.

class getIP
{
    public getIP()
    {

        IPAddress ip = Dns.GetHostEntry("whybla01").AddressList.Where(o => o.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork).First();
        Console.WriteLine(ip);
        string name = Dns.GetHostEntry(ip).HostName.ToString();
        Console.WriteLine(name);
    }
}

How to get full host name in C#?

You can use System.Net.Dns.GetHostEntry:

var fullName = System.Net.Dns.GetHostEntry(string.Empty).HostName;

If an empty string is passed as the hostNameOrAddress argument, then this method returns the IPv4 and IPv6 addresses of the local host.
