This action creates an allocation with strong consistency. The returned CIDR will not overlap with any other allocations from the same pool.


This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginAllocateIpamPoolCidr and EndAllocateIpamPoolCidr.
