Create and manage VPC

KakaoCloud's VPC (Virtual Private Cloud) is a user-defined private network service. By using VPC, users can quickly and easily build a network suited to their environment by combining various network components.
This guide explains how to create and manage VPCs in the VPC service.

Permissions
  • VPC role management follows IAM-based access control (RBAC), and only Project Admin can create and manage VPCs. Other project members can only view the VPC.
  • For information about your IAM permissions, please contact your Org Admin.

Create VPC​

You can create a new VPC.

info

A maximum of 3 VPCs can be created per project. The created VPC will be a default VPC with an automatically included default routing table.

  2. Select the VPC menu, then select the [Create VPC] button.

  3. In the Create VPC screen, enter VPC information, availability zone, and subnet settings, then select the [Create] button.

Rename VPC​

You can rename the VPC.

  1. Go to the KakaoCloud console > VPC menu.

Configure DNS resolver query logging​

You can configure query logging for the DNS resolver within a VPC.

Enable DNS resolver query logging​

To enable DNS resolver query logging for a specified VPC, you must first create an Object Storage bucket to store log files and an S3 access key required for authentication. Refer to DNS resolver query logging for instructions on how to create them.

Follow the steps below to enable DNS resolver query logging:

  1. Go to KakaoCloud console > Beyond Networking Service > VPC.

  2. Click the VPC menu, then click the [More] icon for the VPC where you want to enable DNS resolver query logging, and select Configure DNS resolver query logging.

  3. In the Configure DNS resolver query logging popup, click the current [Disabled] setting to change it to [Enabled].

  4. In the Configure DNS resolver query logging popup, under [Select bucket], choose the Object Storage bucket to store the log files. You can set whether to enable encryption for the selected bucket. For security, it is recommended to select Enable when creating the bucket. For more information on creating Object Storage buckets, refer to the Object Storage > Create and manage bucket document.

  5. Under [Select S3 access key], choose the pre-created S3 access key.

  6. Click [Apply] to enable the setting.

info
  • If the Object Storage bucket designated as the log storage target is deleted, query logs will not be stored correctly. If you have deleted the bucket, reconfigure the setting with a new bucket.
  • If the account permissions change while DNS resolver query logging is enabled, query logs may not be stored correctly. Reassign the necessary permissions to the account that configured DNS resolver query logging.
  • VPCs created before the feature release on June 12, 2025, will be gradually migrated to support this feature. For related inquiries, contact the Helpdesk.

Disable DNS resolver query logging​

Follow the steps below to disable DNS resolver query logging:

  1. Go to KakaoCloud console > Beyond Networking Service > VPC.

  2. Click the VPC menu, then click the [More] icon for the VPC where DNS resolver query logging is currently enabled, and select Configure DNS resolver query logging.

  3. In the Configure DNS resolver query logging popup, review the message and click [Yes].

  4. In the popup, click the current [Enabled] setting to change it to [Disabled].

  5. Click [Apply].

Delete VPC​

You can delete a VPC that is no longer needed.

  1. Go to the KakaoCloud console > Beyond Networking Service > VPC menu.
  2. Select the VPC menu, then select the [More Options] icon for the VPC you want to delete > Delete VPC.
  3. In the Delete VPC popup, enter the VPC name and select [Delete].
