Will I lose my static ip on restarting lightsail ubuntu instance

0

There is conflicting information: some docs say your static ip will only be "saved" if you started the instance on EC2 to begin with. some say you will retain the static ip on lightsail even if you reboot it.

  1. will static ip for lightsail -ubuntu be saved for reboot ?

  2. will static ip for lightsail -ubuntu be saved for start and stop ?

how can i reserve the allocated ip through both 1 and 2 above? TIA

Hello,

Thank you for your questions,

Applies to Lightsail:

We can answer 1 and 2 by quoting the official Lightsail documentation, "The default dynamic public IP address attached to your Amazon Lightsail instance changes every time you stop and restart the instance. Create a static IP address and attach it to your instance to keep the public IP address from changing"

You can follow steps in docs [1] to create a static IP that does not change.

Applies to EC2:

For EC2 the default public IP will change on stop/start but retained during reboots, to preserve the IP during stop/starts you can attached an Elastic IP to the instance [2]

Hope this helps, let me know if there is anything further.
