Currently IPAM does not appear to recognize or support the usage of SuperScopes configured on Microsoft servers. This shortfall results in inaccurate reporting of available address space in my environment and diminishes the appeal of the tool to manage address space in a large environment. I currently have several non-contiguous /24 blocks in one of my large offices broken down by floor. IPAM reports almost all of these blocks at nearly 100% utilized when in fact sufficient address space exists in each SuperScopes. I had submitted a case online regarding trend analysis in IPAM (241976), at its core is the alleged depletion of address space as a result of the inability to see SuperScopes in IPAM.
Sorry for the delayed response. I saw this after your post in the IPAM Importing thread. I've logged the request and will consider this is a future release.
