How to Reserve a Static IP Address on Google Cloud Platform

By Chiranjit Bera Last updated Apr 3, 2020

Whenever we create a new VM (virtual machine) Instance on Google Cloud Platform, an external IP address gets assigned on our VM Instance automatically and that IP address sets as an Ephemeral IP address by default. This IP address we need to save on our Cloud DNS section and the problem is, the IP address changes every time whenever our virtual machine stopped or restarted. That’s why we need to reserve a Static IP address instated of default ephemeral IP address to save our website from technical errors.
