The IPAM feature in Azure Virtual Network Manager works through the following key components:

- Managing IP Address Pools

47
- Allocating IP addresses to Azure resources

### Manage IP address pools
44
54
45
-
IPAM allows network administrators to plan and organize IP address usage by creating pools with address spaces and respective sizes. These pools act as containers for groups of CIDRs, enabling logical grouping for specific networking purposes. You can create a structured hierarchy of pools by dividing a larger pool into smaller, more manageable pools. This hierarchy provides more granular control and organization of your network's IP address space.

There are two types of pools in IPAM:
60
+
48
61
-**Root pool**: The first pool created in your instance is the root pool. This represents your entire IP address range.
49
-
-**Child pool**: A child pool is a subset of the root pool or another child pool. You can create multiple child pools within a root pool or another child pool. You can have up to seven layers of pools

### Allocating IP addresses to Azure resources
52
66
53
-
You can allocate Azure resources, such as virtual networks, to a specific pool with CIDRs. This helps in identifying which CIDRs are currently in use. There's also the option to allocate static CIDRs to a pool, useful for occupying CIDRs that are either not currently in use within Azure or are part of Azure resources not yet supported by the IPAM service. Allocated CIDRs are released back to the pool if the associated resource is removed or deleted, ensuring efficient utilization and management of the IP space.

### Delegating permissions for IPAM
56
72
57
-
With IPAM, you can delegate permission to other users to utilize the IP address pools, ensuring controlled access and management while democratizing pool allocation. These permissions allow users to see the pools they have access to, aiding in choosing the right pool for their needs.

76
59
77
Delegating permissions also allows others to view usage statistics and lists of resources associated with the pool. Within your network manager, complete usage statistics are available including:
60
78
61
79
- The total number of IPs in pool.
80
+
62
81
- The percentage of allocated pool space.
63

Additionally, it shows details for pools and resources associated with pools, giving a complete overview of the IP usages and aiding in better resource management and planning.

85
### Simplifying resource creation
67
86
68
-
When you create CIDR-supporting resources like virtual networks, CIDRs are automatically allocated from the selected pool, simplifying the resource creation process. The system ensures that the automatically allocated CIDRs don't overlap within the pool, maintaining network integrity and preventing conflicts.

## Permission requirements for IPAM in Azure Virtual Network Manager
71
92
72
-
The **IPAM Pool User** role alone is sufficient for delegation when using IPAM. If permission issues arise, you also need to grant **Network Manager Read** access to ensure full discoverability of IP address pools and virtual networks across the Network Manager's scope. Without this role, users with only the **IPAM Pool User** role don't see available pools and virtual networks.
