How to perform "nslookup host server" (3 answers)

Closed 8 years ago.

My website is in an intranet network. I get client Ip Address using following code:

string result=  HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]

Now I want to retrieve client computer name with Ip Address. I can get Client Computer name with nslookup IpAddress in command prompt. I want to implement nslookup in my asp.net website.

How can I do it?
