- you can use release dhcp ethernet x/y on the router to release the current ip given by the DHCP server , and then request for a new one again
But , When you release your current IP address it's up to the DHCP server to decide what IP address you get when you request a new lease. The DHCP server will assign the "next available" IP address, which could even be the address you just released.
If you have control of the DHCP server and don't want the same IP address you can :
- Exclude the unwanted IP address from the pool of available DHCP leases so that the DHCP server won't assign the address.
- Create a DHCP reservation assigning the address you want to the MAC address of your network adapter. or if you have no access to the server Avoid DHCP altogether and assign a static IP address.
