Represents an IP address range using a glob-style syntax ``x.x.x-y.*``
Individual octets can be represented using the following shortcuts :
1. ``*`` - the asterisk octet (represents values ``0`` through ``255``)
2. ``x-y`` - the hyphenated octet (represents values ``x`` through ``y``)
A few basic rules also apply :
1. ``x`` must always be less than ``y``, therefore :
- ``x`` can only be ``0`` through ``254``
- ``y`` can only be ``1`` through ``255``
2. only one hyphenated octet per IP glob is allowed
3. only asterisks are permitted after a hyphenated octet
Examples:
+------------------+------------------------------+
| IP glob | Description |
+==================+==============================+
| ``192.0.2.1`` | a single address |
+------------------+------------------------------+
| ``192.0.2.0-31`` | 32 addresses |

| ``192.0.2.*`` | 256 addresses |

.. note :: \
IP glob ranges are not directly equivalent to CIDR blocks. \
They can represent address ranges that do not fall on strict bit mask \
boundaries. They are suitable for use in configuration files, being \
more obvious and readable than their CIDR counterparts, especially for \
admins and end users with little or no networking knowledge or \
experience. All CIDR addresses can always be represented as IP globs \
but the reverse is not always true.

<title>Internet Protocol Version 6 Address Space</title>
<updated>2019-09-13</updated>
<note>The IPv6 address management function was formally delegated to
IANA in December 1995 <xref type="rfc" data="rfc1881"/>. The registration procedure
was confirmed with the IETF Chair in March 2010.
As stated in RFC3513, IANA should limit its allocation of IPv6-unicast
address space to the range of addresses that start with binary value 001.
The rest of the global unicast address space (approximately 85% of the IPv6
address space) is reserved for future definition and use, and is not to be
assigned by IANA at this time.
While <xref type="rfc" data="rfc3513"/> was obsoleted by <xref type="rfc" data="rfc4291"/>,
the guidiance provided to IANA did not change regarding the allocation of IPv6
unicast addresses.
