IP addresses

[Andrew_Fryer]

Hello,

Given an IP address is it possible to determine whether or not the user of that IP address is online?

Thanks

Andrew

Go to a DOS prompt (home sweet home) and type "ping " and then the IP address or DNS name. If you get back command or file name, go to the windows directory.

For more info though, type "tracert " and then the IP address. that will trace packets through all the servers and routers between you and the IP you are tracing.

If you are on the same LAN as the IP you're after, try "nbtstat -A " and then the IP. That will give you NetBIOS table stats and show the current user's name and the computer name and all that good stuff.

Here is a sample that does not use DOS to do its dirty work. I hae not tried it personally, but Randy Birch does some nice coding
