Clarify the class B and C network limitations

[gukoff]

There's a limitation for the AI Foundry Projects that use network injection:

Subnet IP address limitation: only class B and C are supported

What exactly does this mean? Is it the literal meaning:

Or specifically the private IP ranges?

I am asking because I am able to deploy this sample using VNet 172.16.0.0/24 but the deployment of a Foundry Project hangs with InternalServerError when I try VNet 173.16.0.0/16 (which is still class B, but not reserved for private networking).

What we mean by this is the Private IP4 addresses. A subnet with the range 10.0.0.0/8 is only supported in a limited # of regions. We plan to unlock all regions soon. If you are blocked by this and require a subnet specified with the Class A range, then please respond back to this comment. Thanks!

Amazing, thank you. We have requested an exception to use Class A last week following the instructions here :)
