GKE public endpoint - will it change?

Question

I have a GKE cluster that has a public IP for the master. For example, when I run gcloud container clusters describe, I see a line like below:

publicEndpoint: 34.68.128.12

Questions:

1. Does the public IP change arbitrarily?
2. If the answer is Yes, can it be fixed?

Answer 1

I believe public endpoints on GKE are immutable, so it will not change.
