1. Introduction
An elastic IP pool is a resource pool that contains public IP addresses (IPv4 or IPv6) purchased from an ISP. It must be associated with an edge, so that resources in the VPC connected to that edge can use elastic IP addresses within that range and be accessed from the internet.
2. Prerequisites
• A public IP range (IPv4 or IPv6) purchased from an ISP has been obtained.
• A line type (such as Internet or Direct Line) has been created. For an IPv6 elastic IP pool, the BGP configuration must be complete.
• An edge has been created and is in normal status. (For details about how to create an edge, see section 1 of the Edge Creation and Management Manual.)
3. Constraints and Restrictions
• After an elastic IP pool is created, it cannot be deleted if it contains IP addresses that are in use.
• An elastic IP pool can be associated with only one line type.
• An IPv6 elastic IP pool can work properly only after its BGP configuration is complete.
4. Steps
Step 1.Log in to SCP and go to Networking > IP and Bandwidth > Elastic IP Pools.
Step 2.Click New on the IPv4 or IPv6 tab. The Create Elastic IP Pool-IPv4 or Create Elastic IP Pool-IPv6 pop-up window appears.
Step 3.Configure the fields as instructed in the table below:
| Field |
Description |
Operation Suggestion |
| Name |
Specify a name that reflects the attributes (such as the network segment, line type, and IP type) of the elastic IP pool. |
Format: Line Type - IP Type - IP Pool - Number (Example: Internet - IPv4 - Elastic IP Pool - 01) |
| Description (optional) |
Provide information such as the use, IP range, and business scenario of the elastic IP pool. |
Example: This is an IPv4 elastic IP pool used for internet business. It contains IP addresses ranging from 10.10.10.20 to 10.10.10.50 and allows public access to e-commerce platforms. |
| Tenant |
Specify the tenants associated with the elastic IP pool. If you select All tenants, all tenants can use the elastic IP pool. |
Select a specific tenant if the elastic IP pool is created only for that tenant's use. Select All tenants if the elastic IP pool is created as a resource pool available to all platform users. |
| Line Type |
Select the line type to be associated with the elastic IP pool. |
Select a line type based on the business scenario. (For example, if the elastic IP pool is used for e-commerce business, select Internet. If it is used for internal business, select Direct Line.) |
| Connected To |
Select the gateway to which the elastic IP pool is connected. If All is selected, the pool will be connected to all gateways. If Specified is selected, the pool will be connected only to the specified gateway. |
Select Specified if you want to connect the elastic IP pool only to a specific gateway. Otherwise, select All. |
| Bandwidth |
Enter the bandwidth (in Mbps) provided by the ISP. (This field is required for bandwidth management on SCP.) |
Enter the actual bandwidth. (If the bandwidth provided by the ISP is 1000 Mbps, enter 1000.) |
| IPv4 Range (IPv4 pool) |
Enter the purchased public IP ranges, including the netmask and default gateway of each IP range, to ensure network connectivity to the elastic IP pool. |
Enter the public IP ranges (such as 10.10.10.20-10.10.10.50) assigned by the ISP, and the corresponding netmasks (such as 255.255.255.0) and gateway addresses (such as 10.10.10.1). |
| VLAN ID (IPv4 pool) |
Enter the VLAN ID of the physical switch to enable VLAN isolation or Trunk mode. (Trunk all will be used by default if unspecified.) |
Enter the VLAN ID if VLAN isolation is required on the physical network. Otherwise, leave this field blank. |
| Subnet (IPv6 pool) |
Specify IPv6 global unicast IP ranges or prefixes. This field takes effect after BGP configuration is complete. |
Configure this field after enabling IPv6 global unicast for the subnet, and the specified IP ranges must be global unicast IP ranges. |
Step 4.After the configuration is complete, click OK to complete the creation of the elastic IP pool.
Elastic IP Pool Editing
1. Introduction
When editing an elastic IP pool, you can modify its basic information (such as the name, description, tenant, line type, and bandwidth) to suit changing business needs (such as line type adjustment and bandwidth expansion).
2. Prerequisites
• An elastic IP pool has been created, and IP addresses in this pool have not been modified. (If IP addresses in the pool are already in use, some fields may not be editable.)
3. Steps
Step 1.Log in to SCP and go to Networking > IP and Bandwidth > Elastic IP Pools.
Step 2.Find the target elastic IP pool and click Edit in the Operation column.
Step 3.In the pop-up window that appears, modify the field values as instructed in the table below. (The rules are the same as those described in Elastic IP Pool Creation.)
| Field |
Description |
Operation Suggestion |
| Name |
You can change the name of the elastic IP pool to adapt to business changes. |
Use a new name that is more business-related. |
| Description (optional) |
Provide additional information about the latest uses or application scenarios of the elastic IP pool. |
Update the description as needed for easy management. |
| Tenant |
Change the tenants associated with the elastic IP pool according to changes in resource isolation or sharing requirements. |
Change the specified tenant as needed, or select All tenants if the elastic IP pool is available to all platform users. |
| Line Type |
Change the line type associated with the elastic IP pool to match changes in business scenarios. |
Select a line type based on the new business scenarios. |
| Bandwidth |
Modify the value to match bandwidth changes. |
If the bandwidth provided by the ISP has been changed, enter the new bandwidth. |
Step 4.Click OK to save the changes.
Elastic IP Pool Deletion
1. Introduction
You can delete an unused elastic IP pool to release IP addresses in it. This operation applies to scenarios such as business decommissioning and resource reorganization.
2. Prerequisites
• IP addresses in the elastic IP pool are not in use (not assigned to VMs, routers, or other devices).
3. Steps
Step 1.Log in to SCP and go to Networking > IP and Bandwidth > Elastic IP Pools.
Step 2.Find the target elastic IP pool and click Delete in the Operation column.
Step 3.In the pop-up window that appears, click OK to confirm the deletion of the elastic IP pool.
