This page describes how to view and implement recommendations about when to remove
the IP address range of 0.0.0.0/0 from authorized networks.
Instances with 0.0.0.0/0 in authorized networks accept connections from all internet IPs. This recommender is called Remove broad public access.
Every day, this recommender
proactively detects instances that have broad public IP address ranges and provides insights and recommendations to improve
your instance security. You can view insights and detailed recommendations about instances that have public IP address
ranges enabled and are vulnerable to security breaches by using the Google Cloud console,
gcloud CLI, or the Recommender API.
