## IANA IPv4 Special-Purpose Address Registry

### Description

This dataset contains the registry of special address space assignments for IPv4 IP addresses, as set by IANA. It consists of a data.frame containing the columns:

- `address_block`: the full IPv4 range (chr) (e.g. "11.0.0.0/8")

- `name`: the descriptive name for the special-purpose address block

- `rfc`: the Request for Comment (RfC) through which the special-purpose address block was requested

- `allocation_date`: the allocation date of the block, stored as YYYY-MM.

- `source`: whether an address from the allocated special-purpose address block is valid when used as the source address of an IP datagram that transits two devices (`TRUE`) or not (`FALSE`).

- `destination`: whether an address from the allocated special-purpose address block is valid when used as the destination address of an IP datagram that transits two devices (`TRUE`) or not (`FALSE`).

- `forwardable`: whether a router may forward an IP datagram whose destination address is drawn from the allocated special-purpose address block between external interfaces (`TRUE`) or not (`FALSE`).

- `global`: whether an IP datagram whose destination address is drawn from the allocated special-purpose address block is forwardable beyond a specified administrative domain (`TRUE`) or not (`FALSE`).

- `reserved_by_protocol`. whether the special-purpose address block is reserved by IP, itself. This value is `TRUE` if the RFC that created the special-purpose address block requires all compliant IP implementations to behave in a special way when processing packets either to or from addresses contained by the address block, and `FALSE` otherwise.
