NSX-T Data Center REST API

Create subnet of specified size within an IP block (Deprecated)

Carves out a subnet of requested size from the specified IP block. The "size"
parameter and the "block_id " are the requireds field while invoking this API.
If the IP block has sufficient resources/space to allocate a subnet of specified size,
the response will contain all the details of the newly created subnet including the
display_name, description, cidr & allocation_ranges. Returns a conflict error
if the IP block does not have enough resources/space to allocate a subnet of
the requested size.
Deprecated:
This rest routine is deprecated. Use /infra/ip-pools//ip-subnets/ with method type as PATCH to create a subnet of specified size within an IP address block. Use resourcetype as IpAddressPoolBlockSubnet.
