DHCP question

[looktall]

But question is, so “reserving” the IP address will ensure it never changes the same as setting static and changing the Pool?

When devices are set to use dhcp they request an address from the dhcp server.
The server gives them an available address from the pool.
The next time the device requests an address it will ask for the same address if it's available.
This is why your existing devices kept the same IP addresses on the new router (if the router used a different network address, say 192.xxx.xxx.xxx they would have all got new 192 addresses.)

When you reserve an IP address the dhcp server will only give that address to the device it was reserved for, based on the device's MAC address.
Additionally the address will never change.
Unlike unreserved addresses which can be used for any device.

Thank you so much for that explanation
