How to learn machine name and username by using IP adress

[Sokka93]

How can I learn a computer's machine name and user name by using IP adress? Can you help me please? Thanks in advance.

An IP Address won't reveal that information unless your application is on the target machine. If it is, you wouldn't use the IP address either way. Why do you keep changing your forum name?

[Sokka93]

I don't know first I used my real name then I decided not to use my real name. Thanks for the answer :)

I have to go I have a roll call.

you can lookup the host name of a computer on a network like this:

System.Net.Dns.GetHostEntry("127.0.0.1").HostName

[Dave Kreskowiak]

That will give you the DNS hostname, not necessarily the Windows Computer Name.

The code works for my computer's IP address but when I try an another IP address it gives the IP address of the target computer.

[Sokka93]

Here is the code It works. :D Thank you.

System.Net.Dns.GetHostByAddress(IPaddress).HostName.ToString();

But I have an another problem. I can't send ping every computers. Can you help me with it?

[Dave Kreskowiak]

My.Computer.Network.Ping[^]. BTW, pinging a machine only tells you in the network stack of the target computer is working, up to a certain point, and that's only IF it doesn't have a firewall blocking ICMP traffic. It will NOT tell you if the target server you're trying to connect to is actually listening.
