A block of IPv4/IPv6 addresses defined by a start address and a mask/prefix (network CIDR). An IP block is typically large & allocated to a tenant for automated consumption. An IP block is always a contiguous address space, for example 192.0.0.1/8. An IP block can be further subdivided into subnets called IP block subnets. These IP block subnets can later be added to IP pools and used for IP allocation. An IP pool is typically a collection of subnets that are often not a contiguous address space. Clients are allocated IP addresses only from IP pools.

array of ResourceLink | Readonly |
| _protection | Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true.

string | Readonly |
| _revision | Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected. |
