If your device reboots - new IP.

Based on the DHCP lease time, maybe you'll get back the same address. So...
Possibly - if only ONE SIDE goes down - the reservation will be "held" by the other side.
Modem be like - I'm on a UPS and you went down. I last had 192.168.0.30 - give it back.
If the modem isn't on a UPS and goes down - but the ISP is up - provided someone else doesn't come and grab your IP - you may get it back.
However....
Your ISP may be like - well - I rebooted. I see lots of people online. I can't be bothered to find out who had what - first come first served.
But yeah. Maybe. Maybe not.
Knowing the solution doesn't mean knowing the method. Yet answering correctly and regurgitation are considered "learning" and "knowledge".
