 Cidr
 ==

 Validates that a value is a valid CIDR notation. By default, this will validate
 the CIDR's IP and netmask both for version 4 and version 6, with the option of allowing
 only one type of IP version to be valid. It also supports a minimum and maximum range
 constraint in which the value of the netmask is valid.

 ``message``
 ~~~~~~~~~~~

 **type**: ``string`` **default**: ``This value is not a valid CIDR notation.``

 This message is shown if the string is not a valid CIDR notation.

 ``netmaskMin``
 ~~~~~~~~~~~

 **type**: ``integer`` **default**: ``0``

 It's a constraint for the lowest value a valid netmask may have.

 ``netmaskMax``
 ~~~~~~~~~~~

 **type**: ``string`` **default**: ``32 for IPv4 or 128 for IPv6``

 It's a constraint for the biggest value a valid netmask may have.

 ``netmaskRangeViolationMessage``
 ~~~~~~~~~~~

 **type**: ``string`` **default**: ``The value of the netmask should be between {{ min }} and {{ max }}.``

 This message is shown if the value of the CIDR's netmask is bigger then the value of the `max_` or lower than
 the value of the `min_`.

 You can use the following parameters in this message:

 ===============  ==============================================================
 Parameter        Description
 ===============  ==============================================================
 ``{{ min }}``  The minimum value a CIDR netmask may have
 ``{{ max }}``  The maximum value a CIDR netmask may have
 ===============  ==============================================================

 .. include:: /reference/constraints/_payload-option.rst.inc

 ``version``
 ~~~~~~~~~~~

 **type**: ``string`` **default**: ``all``

 This determines exactly *how* the CIDR notation is validated and can take one
 of a variety of different values:

 **All ranges**

 ``4``
    Validates for CIDR notations that have an IPv4.
 ``6``
    Validates for CIDR notations that have an IPv6.
 ``all``
    Validates all CIDR formats
