How to learn machine name and username by using IP adress

[Sokka93]

I have to go I have a roll call.

[Jimmanuel]

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.
