Techniques and technologies for an Internet Protocol (IP) address management (IPAM) system to track and manage IP address workflows in a network. The IPAM system can be used to define and enforce management policies or rules regarding IP address management, such as allocation policies, refill policies, and so forth. For instance, the IPAM system can enforce allocation policies that define rules to allow or deny allocation of IP addresses based on types of resources for which the IP addresses are requested, registered user accounts that are requesting the IP addresses, the purpose of the resources receiving the IP addresses, and so forth. Additionally, the IPAM system can enforce refill policies that define rules for replenishing inventories of IP addresses that have been allocated for different domains in the network. The IPAM system can improve the management of IP address workflows by enforcing policy and tracking IP address workflows in networks.

Managing the allocations and assignments of internet protocol (IP) addresses for computing resource networks

Techniques and technologies for an IP address management (IPAM) system to monitor the usage of IP addresses across regions in one or more networks of resources. The IPAM system may be used to allocate IP addresses to resources in networks and track what IP addresses are being used by resources or available for allocation. The IPAM system may periodically obtain usage information that indicates actual, current IP address usage by the resources in the networks, identify differences between the current IP address usage and an inventory maintained by the IPAM service, and reconcile the differences. Additionally, the IPAM system may further respond to network administrator queries about their resource and IP address usage. Further, the IPAM system may emit various utilization metrics to the network administrators which may be tied to alarms or alerts around non-compliant resources or IP addresses.

Managing the usage of internet protocol (IP) addresses for computing resource networks

Disclosed are various embodiments for managing network address allocations using prefix allocation trees. In one embodiment, a request is received to allocate a particular network address block. The request specifies one or more attributes and at least one of a prefix or a size for the particular network address block. A prefix allocation tree is updated to indicate that the particular network address block corresponding to the prefix is allocated instead of free and to associate the attribute(s) with the particular network address block. An identification of an allocation of the network address block is returned in response to the request to allocate the particular network address block. An attribute index of the prefix allocation tree is updated asynchronously to index the attribute(s) in association with the particular network address block.

Network address allocation management using prefix allocation trees with asynchronous workflows

Disclosed are various embodiments for distributed network address allocation management. In one embodiment, a first instance of a plurality of instances of an allocation management service assigns a first portion of a network address space to the first instance and a second portion of the network address space to a second instance of the plurality of instances. The second instance receives a request to allocate a particular network address block. The second instance allocates the particular network address block from the second portion of the network address space by updating an allocation data structure. An allocation of the particular network address block is returned in response to the request. A copy of the allocation data structure maintained by the first instance is updated asynchronously based at least in part on the allocation of the particular network address block.
