Ever wanted to know exactly how many computers are connected to your wireless network? Want all the MAC addresses and IP addresses for the computers connected to your wireless network?
If so, then you are probably doing so for security reasons. Wireless networks are constantly being hacked in order to gain access to confidential information. If you’re a home user, your wireless network may be used by your neighbors to get free Internet at your expense.
Whatever the reason may be, it’s sometimes good to know who exactly is connected to your wireless network. Once you know, you can possibly prevent unauthorized users from accessing your router.
ZamZom is a free program that scans your network and spits out the IP address and MAC address for all computers or devices connected to your network. Also, check out a previous post I wrote about another free network scanner from SoftPerfect.
To use the program, just install it and then click on the Fast Scan button.
It will automatically grab your IP address, computer name, IP Address, and the wireless IP address range for your network.
If you feel that not all the computers have shown up in the list, click the Deep Scan button and the program will take longer, but should find every networked device.
Overall, the program is pretty straight-forward and gets the job done. If you are looking for a more advanced tool for your IT department, you may want to checkout GFI LANGuard, a software suite that scans the entire network for security vulnerabilities. Enjoy! [via BlogsDNA]



hmm…
nice little program. so the question is: can i use this even if i'm not admin ?
Or you could just check your router.
….or you could just type arp -a from the command line?
# arp -a
Net to Media Table: IPv4
Device IP Address Mask Flags Phys Addr

This works in windows, as well.
Why not just look at the DHCP leases on your router? No third party software needed.
Geekmaster:
For arp – a to show the devices on the loal network the hoats actually have to have sent data to each other. In other words the hosts must have contacted each other at some point in time.
Try this….run arp -a and look at the output then put a host on the network without "talking" to it. run arp -a again and you won't see it.
Ping it and then run arp -a again and it will show up.
I think that's why this program works. It must ping all adresses in the net range and then arp -a to see what shows.
