Overlapping blocks #41
Comments
Hi there @letmetechyou, this is exactly the use case for a difference Space. Spaces are a collection of UNIQUE IP addresses. As such, the blocks within them will not overlap. For your case where you intentionally have overlapping IP space, you would create another space, thereby representing a different grouping of non-overlapping IP space, and add the overlapping Block in there. If you've ever used other solutions such as Infoblox, this about this like Namespaces or IP Spaces (for BloxOne). Does that makes sense? P.S. As an outcome of this, I'll be adding a "concepts" section to the readme to better explain Spaces, Blocks, etc. and how to properly leverage them in context within Azure IPAM. |
Yea this makes sense thanks. Are there any plans to add a section to section to show all the available subnets in a pool of addresses or just some way to see an overall hierarchy of all the addresses and whats used. would be nice to see what spaces are available in a block |
Can you elaborate just a bit @letmetechyou? Are you looking for something more API-driven, or visual? Today, we do have a visualization that allows you to drill-down, but it uses the constructs in IPAM (space/block/vnet/subnet/etc) to display the relationships. Also in the Discovery section, we show all of the vNET's that exist, and in the Subnets section we list the parent vNET for every Subnet that exists. Help me understand a bit more specifically what you're looking for, and I'll let you know if there's already a way to accomplish that, if it's something we can add into the project roadmap and an ETA. Thanks! |
Yea but it just shows what’s allocated and not what’s available. Which kinda makes it difficult to use for ip address planning since you have to drill down into each space and each subnet. Kinda of like how phpipam or some of the other solutions gives you an overall view of what's going on in the environment ip allocation wise.

Here's an example of the visualizations currently available:

So what you're saying is a view of vNET's showing what space is not currently allocated from each vNET. Is that right? |
and also could help maybe viewing and verifying these subnets are not used in other parts of azure. |
Hi @letmetechyou, I've moved this to Discussion #50 as it makes for sense here, and this is a great idea. Thanks! |
Whats a way to go about adding a cidr that overlaps with another subnet but neither vnet will be peered.
