IP Address Manager (IPAM) enables global management of IP addresses. After you create an IPAM, you can create a private scope for the IPAM. Each private scope represents an independent address scope. You can create IPAM pools in a private scope to manage and assign IP addresses. This topic describes how to create and manage an IPAM and its private scopes.
Create an IPAM
Log on to the IPAM console.
In the top navigation bar, select the region where you want to create an IPAM.
On the IPAM page, click Create IPAM. Specify the following parameters. You can use the default values or custom values for other parameters.
Parameter
Description
Effective Region
Select an effective region for the IPAM.
You must select at least one effective region and the effective regions must include the region where the IPAM is deployed.
NoteYou cannot delete the region where the IPAM is deployed.
Create a private scope
Before you create a scope, note the following information:
After you create an IPAM, the system automatically creates a public scope and a private scope. You cannot delete the private or public scope.
The public scope cannot be allocated or used.
You can create only private scopes.
CIDR blocks within the same scope cannot overlap with each other. CIDR blocks in different scopes can overlap with each other.
Log on to the IPAM console.
In the top navigation bar, select the region where you want to create a scope. In the navigation pane on the left, click IPAM Scope.
On the IPAM Scope page, click Create Scope. Specify the following parameters. You can use the default values or custom values for other parameters.
Parameter
Description
IPAM
The system automatically displays the IPAM to which the scope belongs.
Scope Type
The system automatically displays the scope type. Only Private is supported.
Resource monitoring
IPAM provides monitoring for IP addresses, including continuous monitoring for IP address usage, CIDR block compliance, and address conflicts. This ensures that you can expand your pool, handle IP address conflicts, improve address usage, and enhance network stability and security.
On the IPAM Scope page, click the IPAM scope ID or click Manage in the Actions column to view the following information about the IPAM scope: resource CIDR blocks, management status, overlapping status, and compliance status.
Overview: Click the Overview tab to view the following information within the private scope: resource CIDR blocks, management status, overlap status, and compliance status. The information is displayed in doughnut charts.
Resource Management: Click the Resource Management tab to view the following information within the private scope: resource types, CIDR blocks, management status, compliance status, overlap status, and address usage. When there are overlapping CIDR blocks, click Overlap Status > View to see the instances that conflict with existing resources.
VPC Resource: Click the VPC ID to view the following information within the private scope: CIDR block allocation, overlap status, and VPC address usage.
VSwitch Resource: Click the vSwitch ID to view the following information within the private scope: CIDR block usage, IP address usage, and total number of IP addresses.
IPAM Pool: Click the IPAM Pool tab to view the following information about the pool: the effective region, CIDR blocks, and IP version.
Monitoring Chart: Click the Monitoring Chart tab to view the following information within the private scope in a time series chart: management status, overlap status, compliance status, and number of CIDR blocks.
What to do next
Log on to the IPAM console.
In the top navigation bar, select the region of the IPAM.
You can perform the following operations as needed.
Add and delete an effective region
On the IPAM page, find the IPAM and use one of the following methods to add an effective region:
Click the IPAM ID. On the Effective Region tab, click Add Effective Region.
In the Actions column, click Manage. On the Effective Region tab, click Add Effective Region.
In the Actions column, choose
> Add Effective Region.
To delete an effective region, find the region on the Effective Region tab and click Delete in the Actions column.
Before you delete an effective region, note the following information:
You cannot delete the region where the IPAM is deployed.
Make sure that all IPAM pools in the region are deleted. For more information about how to delete an IPAM pool, see Create and manage IPAM pools.
Add and delete a scope
Find the target IPAM, and in the Actions column, choose
> Add Scope.In the Create Scope dialog box, set the required parameters to create a private scope. For more information, see Create a private scope.
To delete a scope, find the scope and click Delete in the Actions column.
Before you delete an IPAM scope, note the following information:
The public scope and private scope created by the system cannot be deleted.
Make sure that all IPAM pools within the scope are deleted. For more information about how to delete an IPAM pool, see Delete an IPAM pool.
