# What is IP address management in Azure Virtual Network Manager?
In this article, you learn about the IP address management (IPAM) feature in Azure Virtual Network Manager and how it can help you manage IP addresses in your virtual networks. With Azure Virtual Network Manager's IP Address Management (IPAM), you can create pools for IP address planning, automatically assign nonoverlapping classless inter-domain routing (CIDR) addresses to Azure resources, and prevent address space conflicts across on-premises and multicloud environments.

### Manage IP address pools

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, dividing a larger pool into smaller, more manageable pools, aiding in more granular control and organization of your network's IP address space.

### Allocating IP addresses to Azure resources

-
When it comes to allocation, you can assign Azure resources with CIDRs, such as virtual networks, to a specific pool. 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.

When creating 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.

When using IP address management, the **IPAM Pool User** role alone is sufficient for delegation. During the public preview, 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 won't be able to see available pools and virtual networks.

- When virtual networks are associated with an IPAM pool, peering sync may show as out of sync, even though peering is functioning correctly.

- When a VNet is moved to a different subscription, the references in IPAM are not updated, leading to inconsistent management status.

- When entering an IP address space, the address space entered must be a valid address range (valid starting address and valid size), else a failure will be encountered when sending a request. Currently, the portal does not validate CIDR input prior to sending requests.

For example, you can allocate a CIDR in the pool to the address space in your on-premises environment. Likewise, you can also use this for a space that is used by a Virtual WAN hub or Azure VMware Private Cloud.
