How to check host ip address that is assigned by router using DHCP

Question as above.

What command line do I enter?

Also, my hosts arent getting ip addrersses. What could be the problem?

ip dhcp excluded-address 192.168.1.1
ip dhcp pool testpool
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1

Can someone also answer my thread: http://www.techexams.net/forums/ccna-ccent/89959-question-dhcp-nat.html

It is CCNA level unfortunately

Windows - ipconfig
Linux - ifconfig

Is the fast ethernet port up on the router?
Is the computer on?
Does the fast ethernet port have an ip address?
Is the cable plugged in all the way?

Hi I forgot to say that I am using GNS3, so is there a way to check the ip address assigned?

show ip dhcp binding will show current leases

What are you using for the hosts? If it's the vpcs then you need to set them to request a dhcp ip too.

actually the correct answer is show arp and show ip nat translation from my colleague

but thanks anyway

Show arp shows arp requests i.e. mac address bindings to ip addresses; show ip nat translation shows NAT. Not to be rude but do you see DHCP in either one of those commands? If your colleague told you this then I would recommend never asking him for anything again (you may be able to ask him the directions to the microwave; but you'll probably end up trying to heat your hot pocket up in the company mailbox).

The arp will show what IP is being used by the host. If DHCP is being used then that is the address that has been assigned. The NAT will show the private to public binding. So these commands will give you the info needed in a conveluted way.

Perhaps I did not state what I wanted clearly. Anyway, I solved my problems.

It also gives static address translations; IMO its like asking how to see the running config and his co worker telling him show tech.
