Note that this will only work if there happens to be an arp entry for that MAC on your workstation.

yeah tried that just got the router

run a ping sweep of every IP address on the subnet. I forget the name of the tool but there are tons of them out there. Just search on ping sweep or ping plotter.

Then you can check your arp entries as stated above.

found a program to ping sweep but it didn't pick it up...Awhile ago I accessed the thing through a browser. but doesn't seem like its gonna work now the phone works and its plugged in just can't get it to ping maybe its setup not to respond to pings, so I'm stuck again

well I think I found it I may have set it to 192.168.0.255 is using 255 a bad idea I can ping it, but can't access through the web browser..

isn't 192.168.0.255 a broadcast address?

 

[Fiveohhh]

i don't know I get a ping response from it...

 

[HKSturboKID]

what I usually do when all else fail is write a small batch file with this command and dump the output into a txt file to see who respond and their Mac and IP address.

the command is.

nbtstat -A 192.168.0.1
nbtstat -A 192.168.0.2
nbtstat -A 192.168.0.3
......
nbtstat -A 192.168.0.254

This way you will see their IP, Mac, PC name, who's login, domain or workgroup they are in.

Cruise over to <FONT size=2>http://www.foundstone.com and pick up their SuperScan4 program, it'll scan a whole range of IP addresses and also tell you what services are available on each address.

yes...it is. You can't use it as a usable address.

Since you are pinging the broadcast address all hosts will respond.

Depends, not all IP stacks respond to broadcast pings and I would think the ones that do have it as a configurable option.
