| o Name - A descriptive name for the special-purpose address block. |
| |
| o RFC - The RFC through which the special-purpose address block was |

| 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. |
