This page describes how to use the authorized networks settings for connecting to Cloud SQL instances that use IP addresses.
Configure authorized networks
Your client application's IP address or address range must be configured as
authorized networks
for the following conditions:
- Your client application is connecting directly to a Cloud SQL instance on its public IP address.
- Your client application is connecting directly to a Cloud SQL instance on its private IP address, and your client's IP address is a non-RFC 1918 address
The IP address can be either a single endpoint or consist of a range in CIDR notation.
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Select Connections from the SQL navigation menu.
- Select the Public IP checkbox.
- Click Add network.
- In the Name field, enter a name for a New network.
- In the Network* field, enter the IP address or address
range you want to allow connections from.
Use CIDR notation.
- Click Done.
- Click Save to update the instance.
gcloud
Configuring authorized networks replaces the existing authorized networks list.
gcloud sql instances patch INSTANCE_ID \ --authorized-networks=NETWORK_RANGE_1,NETWORK_RANGE_2...
Terraform
To configure authorized networks, use a Terraform resource.
Apply the changes
To apply your Terraform configuration in a Google Cloud project, complete the following steps:
- Launch Cloud Shell.
-
Set the Google Cloud project where you want to apply the Terraform configuration:
export GOOGLE_CLOUD_PROJECT=PROJECT_ID
-
Create a directory and open a new file in that directory. The filename must have the
.tf
extension, for examplemain.tf
:mkdir DIRECTORY && cd DIRECTORY && nano main.tf
- Copy the sample into
main.tf
. - Review and modify the sample parameters to apply to your environment.
- Save your changes by pressing
Ctrl-x
and theny
. -
Initialize Terraform:
terraform init
-
Review the configuration and verify that the resources that Terraform is going to create or
update match your expectations:
terraform plan
Make corrections to the configuration as necessary.
-
Apply the Terraform configuration by running the following command and entering
yes
at the prompt:terraform apply
Wait until Terraform displays the "Apply complete!" message.
- Open your Google Cloud project to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.
Delete the changes
To delete your changes, do the following:
- To disable deletion protection, in your Terraform configuration file set the
deletion_protection
argument tofalse
.deletion_protection = "false"
- Apply the updated Terraform configuration by running the following command and
entering
yes
at the prompt:terraform apply
-
Remove resources previously applied with your Terraform configuration by running the following command and entering
yes
at the prompt:terraform destroy
REST v1
Configuring authorized networks replaces the existing authorized networks list.
Before using any of the request data, make the following replacements:
- project-id: The project ID
- instance-id: The instance ID
- network_range_1 An authorized ip address or range
- network_range_2 Another authorized ip address or range
HTTP method and URL:
PATCH https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id
Request JSON body:
{ "settings": { "ipConfiguration": { "authorizedNetworks": [{"value": "network_range_1"}, {"value": network_range_2"}] } } }
To send your request, expand one of these options:
You should receive a JSON response similar to the following:

Limitations
Some IP address ranges can't be added as authorized networks.
Address range | Notes |
---|---|
127.0.0.0/8 | Loopback address range |
10.0.0.0/8 | RFC 1918 address range. These are automatically and implicitly included in the authorized networks by Cloud SQL |
172.16.0.0/12 | RFC 1918 address range. These are automatically and implicitly included in the authorized networks by Cloud SQL |
172.17.0.0/16 | Reserved for the Docker bridge network |
192.168.0.0/16 | RFC 1918 address range. These are automatically and implicitly included in the authorized networks by Cloud SQL |
0.0.0.0/8 | RFC 3330 null network |
169.254.0.0/16 | RFC 3927 and RFC 2373, link-local networks |
192.0.2.0/24 | RFC 3330 and RFC 3849, documentation networks |
224.0.0.0/4 | RFC 3330, multicast networks |
240.0.0.0/4 | This block, formerly known as the Class E address space, is reserved for future use; see RFC 1112, Section 4. |
