# Geo/CIDR Map

Available in Classic and VPC

To create a Traffic Policy that uses geolocation or CIDR load balancing algorithms, you must first create a Map that matches the selected algorithm. A Map consists of multiple zones. You can create a Map by assigning regions or IP address ranges to each zone based on your needs. You can apply a created Map to multiple Traffic Policies. You can create and manage Maps in the **Geo/CIDR Map** menu.

## Geo/CIDR map interface

Here is a basic overview of the **Geo/CIDR Map** menu for using Global Traffic Manager. ![gtm-map_screen_ko](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/gtm-map_screen_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A13%3A16Z&se=2026-11-14T06%3A13%3A16Z&sr=c&sp=r&sig=2sR4krg0f0Ppm9rdjSAlCnEYUIZ3DDsn1mv558c6npM%3D)

## Create Geo/CIDR map

Create a Geo Map or CIDR Map depending on the algorithm you want to use.

- [Create Geo Map](/docs/en/gtm-map#GeoMap%EC%83%9D%EC%84%B1): Create a physical Region-based Map to be applied when using the geolocation algorithm.
- [Create CIDR Map](/docs/en/gtm-map#CIDRMap%EC%83%9D%EC%84%B1): Create an IP address-based Map to be applied when using the CIDR algorithm.

### Create Geo map

To create a Geo Map:

1. From the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Global Traffic Manager**.
2. Click the **Geo/CIDR Map** menu.
3. Click the **[Create Geo/CIDR Map]** menu.
4. Enter the **Map name** and select **GEO** in the **Map Type** drop down menu.
5. Enter the name of the Zone and click **[Create]**.
  - **Select map**: Select and load an existing Geo Map.
    - The default Geo Map (DEFAULT_MAP) cannot be loaded.
  - ![i-gtm-menu](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-gtm-menu.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A13%3A16Z&se=2026-11-14T06%3A13%3A16Z&sr=c&sp=r&sig=2sR4krg0f0Ppm9rdjSAlCnEYUIZ3DDsn1mv558c6npM%3D): **Edit** after hovering the mouse over or click **Delete** to edit Zone name or delete Zone.
6. Select by clicking Zone.
7. Select the Region to assign to the Zone and click **[Add]**.
  - You can search by entering the Region name.
  - Click ![i-gtm-more](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-gtm-more.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A13%3A16Z&se=2026-11-14T06%3A13%3A16Z&sr=c&sp=r&sig=2sR4krg0f0Ppm9rdjSAlCnEYUIZ3DDsn1mv558c6npM%3D) to display the detailed Region.
  - Can delete from the Zone by selecting the Region added and clicking **[Delete]**.
8. After repeating steps 5 to 7 to complete adding Zones, click **[Create]**.

              Note

              

You do not need to create a separate Zone for regions that are not assigned to a Zone. A Zone named ETC is created automatically. ETC includes all regions that are not assigned to any Zone.

### Create CIDR map

To create a CIDR Map:

1. From the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Global Traffic Manager**.
2. Click the **Geo/CIDR Map** menu.
3. Click the **[Create Geo/CIDR Map]** menu.
4. Enter the **Map name** and select **CIDR** in the **Map Type**.
5. Enter the CIDR block information and click **[Add]**.
  - **Block name**: Enter a block name.
  - **IP block settings**: Enter the CACHE DNS address ranges queried by clients for each block.
  - ![i-gtm-blockedit](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-gtm-blockedit.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A13%3A16Z&se=2026-11-14T06%3A13%3A16Z&sr=c&sp=r&sig=2sR4krg0f0Ppm9rdjSAlCnEYUIZ3DDsn1mv558c6npM%3D): Click to edit CIDR block settings

6. After repeating step 5 to complete adding CIDR blocks, click **[Create]**.

              Note

              

You do not need to create a separate CIDR block for IP address ranges that are not assigned to a CIDR block. A CIDR block named ETC is created automatically. ETC includes all IP address ranges that are not assigned to any CIDR block.

## Change Geo/CIDR map settings

To change the Zone or CIDR block settings of a created Geo/CIDR Map:

              Note

              

- You cannot change the settings if there is a Traffic Policy linked to the Geo/CIDR Map. First, disconnect the association or delete the Traffic Policy (see [Change Traffic Policy settings](/docs/en/gtm-policy#TrafficPolicy%EC%84%A4%EC%A0%95%EB%B3%80%EA%B2%BD) or [Delete Traffic Policy](/docs/en/gtm-policy#TrafficPolicy%EC%82%AD%EC%A0%9C)).
- The setting in the built-in Geo Map (DEFAULT_MAP) cannot be changed.

1. From the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Global Traffic Manager**.
2. Click the **Geo/CIDR Map** menu.
3. Select a Map to change the setting and click **[Map Settings]**.
4. After changing the setting, click **[Apply]**.
  - For details on the setting, see [Create Geo Map](/docs/en/gtm-map#GeoMap%EC%83%9D%EC%84%B1) or [Create CIDR Map](/docs/en/gtm-map#CIDRMap%EC%83%9D%EC%84%B1).

## Delete Geo/CIDR map

To delete a created Geo/CIDR Map:

              Note

              

- You cannot delete it if there is a Traffic Policy connected to the Geo/CIDR Map. First, disconnect the association or delete the Traffic Policy (see [Change Traffic Policy settings](/docs/en/gtm-policy#TrafficPolicy%EC%84%A4%EC%A0%95%EB%B3%80%EA%B2%BD) or [Delete Traffic Policy](/docs/en/gtm-policy#TrafficPolicy%EC%82%AD%EC%A0%9C)).
- The built-in Geo Map (DEFAULT_MAP) cannot be deleted.

1. From the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Global Traffic Manager**.
2. Click the **Geo/CIDR Map** menu.
3. Select a Map to delete and click **[Delete]**.
4. When the Geo/CIDR Map delete popup appears, click **[Delete]**.
