Static IP addresses in Amazon Lightsail
tl;dr
A static IP is a fixed, public IP address that you can assign and reassign to an instance or other resource. If you haven't set up a static IP address, each time you stop or restart your instance, Lightsail assigns a new public IP address.

If you stop or restart your instance without first creating a static IP address and attaching it to your instance, you lose your IP address when your instance restarts.
