# IP Block

IP Block is a contiguous block of IP addresses defined by a prefix and prefix length.

It can be used by the Provider to describe the overlay network of a particular Site. Providers can also use Allocations to delegate portions of these IP Blocks to Tenants.

Deprecation history:

- `blockSize` was deprecated in favor of `prefixLength` and was removed on April 15th, 2023 0:00 UTC. Please use `prefixLength` instead.
