iana_special_assignments: IANA IPv4 Special-Purpose Address Registry
In iptools: Manipulate, Validate and Resolve 'IP' Addresses

Description Usage Format Note References See Also

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.
