Hi guys, I am in a need to list the IP addresses (and possibly more information) dynamically assigned by DHCP on local subnet from XP MSDOS command prompt.
Is there a way to do this? If not, it is not necessailry from DOS prompt. Help is really appreciated. Thanks!

To see that you would have to login to whatever is doing the DHCP. The configuration for it will list the "scope" (that's what you call the range of IP's DHCP is configured to assign to clients).

Perhaps if you gave us some detail on what it is you are trying to do, we could help you get it done.

Go to a cmd prompt
type ping [the first 3 octets with the 4th being 255]

example: ping 192.168.1.255

now do a arp -a

It will list all computers that responded/are presently live.

This has nothing to do with how the ips were assigned. You would get that info from the dhcp server.

Answers are only as good as the information you provide.

Okay, arp -a displays just number of local networ connections for current workstation from which I am issuing the command. I was inquiring about the all IP addresses assigned by the DHCP in current local subnet. Thx!

No. arp -a lists ip addresses it has resolved and cached

You don't seem to be getting the point both CurtR and I are making. There is no command to list all those getting dhcp ips. You get this information by logging on to the dhcp server and reviewing the current dhcp assignments.

Beyond that you would have to go to each machine and run ipconfig /all to see if set to dhcp is yes or no.
