Hey there,

I just wanted to know if there is any way to find out about the active and open IPs in a DHCP network. It would be really appreciated if you guide me through this.

Thanks,:cool:

Hello,

If you are using a Windows Server, go to control panel and then administrative tools. Choose DNS. Under forward lookup zones, click on your domain name. That will show the current reservations for DNS. You can use something like angryipscanner to scan your network and compare to the server results.

There are a couple ways of doing it. The way mentioned by Joel is correct but you could also go into Administrative Tools>DHCP>Scope>Address Lease

This will show you what IP's are being dished and to what machine!

From any windows machine at the command prompt do the following assuming a 10.0.1.x network.

Ping 10.0.1.255
arp -a

You'll get MAC address and IP address. Might not work if device doesn't respond to a ping.

I would also go into the DHCP management console and look at the address leases.

I will add one more thing to your possibilities as KISS, ITS2006 and Joel have already done so.
