Bug report

Bug description:

According to https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml
and https://en.wikipedia.org/wiki/Reserved_IP_addresses 0.0.0.0/8 and other ranges should be reserved.

ipaddress.IPv4Address("0.0.0.0").is_reserved is False however.

The definition in the Python docs is

is_reserved
    True if the address is otherwise IETF reserved.

So I believe there are several ranges missing.
