1. A string consisting of an IP address and an optional mask, separated by

a slash (``/``). The IP address is the network address, and the mask

can be either a single number, which means it's a *prefix*, or a string

representation of an IPv6 address. If it's the latter, the mask is

interpreted as a *net mask*. If no mask is provided, it's considered to

be ``/128``.

is a single number, which represents a *prefix*. If no mask is provided,

it's considered to be ``/128``.

For example, the following *address* specifications are equivalent:

``2001:db00::0/24`` and ``2001:db00::0/ffff:ff00::``.

Note that currently expanded netmasks are not supported. That means

``2001:db00::0/24`` is a valid argument while ``2001:db00::0/ffff:ff00::``

not.

2. An integer that fits into 128 bits. This is equivalent to a

single-address network, with the network address being *address* and
