Reserved addresses
Most of these functions check if an address or network is reserved for
special use. The exception is is_global(), which checks if it is not
reserved.
A network is considered reserved if both the network_address()
and broadcast_address() are reserved.

Here are hyperlinks to the IANA registries of allocated address space:
IPv4: allocations, special purpose
IPv6: allocations, special purpose
A logical vector
Addresses reserved by IPv6 transition mechanisms can be identified by functions described in ipv6-transition.
