I was working on Retrieving IP address and client machine name for few days

  • 0

I was working on Retrieving IP address and client machine name for few days on the internet (not on the local network)
so I found some ways for getting IP-address , but I couldn’t find a way for getting client machine name or gathering some info about my web site users ?
I know there are many duplicate threads about this issue out there , but many of them are old or do n’t work.
the below server side codes return SERVER NAME Not client computer name ! 

string UserHost_ComputerName4 = Dns.GetHostName();//Server Name
string UserHost_ComputerName5 = Environment.MachineName;//Server Name

and the below line have error on user-side , but it works on server-side page running : 

 string UserHost_ComputerName3 = Dns.GetHostEntry(Request.ServerVariables["REMOTE_ADDR"]).HostName.ToString();//Has Error

Would you lead me to a possible and workable ways (JavaScript or jQuery or server side) for getting client (users who are visiting my web site) machine name?

    As far as I remember, in order to get:

    • Request.ServerVariables["REMOTE_ADDR"]
    • Request.ServerVariables["REMOTE_HOST"]
    • Request.ServerVariables["REMOTE_USER"]

    you have to enable Reverse DNS Lookup for you IIS.

    p.s.
    atm I’m not able to test it myself, so I’m not quite sure if this will solve ur problem
