The IPv4 and IPv6 Special-Purpose Address Registries maintain the
following information regarding each entry:
o Address Block - A block of IPv4 or IPv6 addresses that has been
registered for a special purpose.
o Name - A descriptive name for the special-purpose address block.
o RFC - The RFC through which the special-purpose address block was
requested.
o Allocation Date - The date upon which the special-purpose address
block was allocated.
o Termination Date - The date upon which the allocation is to be
terminated. This field is applicable for limited-use allocations
only.
o Source - A boolean value indicating 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.
o Destination - A boolean value indicating 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.
o Forwardable - A boolean value indicating whether a router may
forward an IP datagram whose destination address is drawn from the
allocated special-purpose address block between external
interfaces.
o Global - A boolean value indicating whether an IP datagram whose
destination address is drawn from the allocated special-purpose
address block is forwardable beyond a specified administrative
domain.
o Reserved-by-Protocol - A boolean value indicating 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.
If the value of "Destination" is FALSE, the values of "Forwardable"
and "Global" must also be false.
