Today, I had a design review meeting about a new small application that I’m participating in its development as an architect. One of the crucial features in this application was depending on the ability to identify the client’s computer name (don’t ask me why…). Since this was a crucial thing for my customer, I decided to write about it. Pay attention that the solution I offer is for intranet application since it is counting on a DNS server.
Get Client Computer Name
In order to retrieve the client’s computer name, you will have to query the DNS server with the client’s IP. The IP can be easily retrieved by using the ASP.NET
Request object with its
Here is a method that returns the computer name by a given IP:
public string GetComputerName(string clientIP)
var hostEntry = Dns.GetHostEntry(clientIP);
catch (Exception ex)
In order to use this method, you’ll have to reference the
System.Net namespace which includes the
Dns class. To consume the method, you can write the following code in your ASP.NET application:
There are rare times that you need to know what is the name of the computer of your client. I showed how to achieve that using the
System.Net.Dns class. Probably there are more solutions to this problem but this one is very easy to implement.
