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.

Check Geo/CIDR map list
To view information about created Geo/CIDR Maps:
- From the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Global Traffic Manager.
- Click the Geo/CIDR Map menu.
- When the Geo/CIDR Map list appears, check summary information or click Geo/CIDR Map to check detailed information.
- Map name: Name entered when creating the map.
- Map Type: Type of map (GEO, CIDR)
- Associated Traffic Policy: Traffic Policy configured using the map.
- Created on: Date and time when the map was created.
- Last modified on: Date and time when the map settings were last modified.
- Geolocation details/CIDR details: Detailed information about the Zones or CIDR blocks configured in the map.
Create Geo/CIDR map
Create a Geo Map or CIDR Map depending on the algorithm you want to use.
- Create Geo Map: Create a physical Region-based Map to be applied when using the geolocation algorithm.
- Create CIDR Map: Create an IP address-based Map to be applied when using the CIDR algorithm.
Create Geo map
To create a Geo Map:
- From the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Global Traffic Manager.
- Click the Geo/CIDR Map menu.
- Click the [Create Geo/CIDR Map] menu.
- Enter the Map name and select GEO in the Map Type drop down menu.
- 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.
: Edit after hovering the mouse over or click Delete to edit Zone name or delete Zone.
- Select map: Select and load an existing Geo Map.
- Select by clicking Zone.
- Select the Region to assign to the Zone and click [Add].
- You can search by entering the Region name.
- Click
to display the detailed Region. - Can delete from the Zone by selecting the Region added and clicking [Delete].
- After repeating steps 5 to 7 to complete adding Zones, click [Create].
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:
- From the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Global Traffic Manager.
- Click the Geo/CIDR Map menu.
- Click the [Create Geo/CIDR Map] menu.
- Enter the Map name and select CIDR in the Map Type.
- 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.
: Click to edit CIDR block settings
: Click to delete CIDR block
- After repeating step 5 to complete adding CIDR blocks, click [Create].
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:
- 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 or Delete Traffic Policy).
- The setting in the built-in Geo Map (DEFAULT_MAP) cannot be changed.
- From the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Global Traffic Manager.
- Click the Geo/CIDR Map menu.
- Select a Map to change the setting and click [Map Settings].
- After changing the setting, click [Apply].
- For details on the setting, see Create Geo Map or Create CIDR Map.
Delete Geo/CIDR map
To delete a created Geo/CIDR Map:
- 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 or Delete Traffic Policy).
- The built-in Geo Map (DEFAULT_MAP) cannot be deleted.
- From the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Global Traffic Manager.
- Click the Geo/CIDR Map menu.
- Select a Map to delete and click [Delete].
- When the Geo/CIDR Map delete popup appears, click [Delete].
