Using CLI
Using CLI
To remediate the “Alias IP Ranges Should Be Enabled” misconfiguration in GCP using GCP CLI, follow these steps:
- Open the Cloud Shell in the GCP Console.
-
Run the following command to list all the VPC networks in your project:
- Identify the VPC network for which you want to enable alias IP ranges.
-
Run the following command to enable alias IP ranges for the identified VPC network:
Replace
[NETWORK_NAME]with the name of the identified VPC network. -
Verify that alias IP ranges have been enabled for the VPC network by running the following command:
Replace
[NETWORK_NAME]with the name of the identified VPC network. The command should return a table with the alias IP ranges for the VPC network. - Repeat steps 3-5 for all other VPC networks in your project.
Using Python
Using Python
To remediate the misconfiguration “Alias IP Ranges Should Be Enabled” in GCP using Python, follow the below steps:Step 1: Import the necessary libraries and authenticate to GCP.Step 2: Get the list of all subnetworks in the project.Step 3: For each subnetwork, check if Alias IP Ranges is enabled. If not, enable it.Step 4: Verify that the Alias IP Ranges is enabled for all subnetworks.This should remediate the misconfiguration “Alias IP Ranges Should Be Enabled” in GCP using Python.
