I need to find out DHCP IPs that Cisco switch issued and the range

We have a cisco switch and I know devices are picking up IPs via DHCP from it. What cisco commands can I use to see what IPs have been given out and what the range is so I can set some static IPs on the same vlan?

When you have figured out what ranges you are using you can use the following command to make sure the static IPs you want to use are not given out by the server.

For one address
ip dhcp excluded-address XXX.XXX.XXX.XXX

For a range of addresses
ip dhcp excluded-address XXX.XXX.XXX.XXX YYY.YYY.YYY.YYY
