     * The following values are possible:
     *
     * - `false` - the address must not have a subnet (default).
     * - `true` - specifying a subnet is optional.
     * @param bool $requireSubnet Whether subnet is required.
     * @param bool $allowNegation Whether an address may have a `!` negation character at the beginning.
     * @param string $incorrectInputMessage A message used when the input it incorrect.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{type}`: the type of the value being validated.
     * @param string $message Error message used when validation fails due to the wrong IP address format.
     *
     * You may use the following placeholders in the message:

     * @param string $ipv4NotAllowedMessage Error message used when validation fails due to the disabled IPv4
     * validation when {@see $allowIpv4} is set.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string $ipv6NotAllowedMessage Error message used when validation fails due to the disabled IPv6
     * validation when {@see $allowIpv6} is set.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string $wrongCidrMessage string Error message used when validation fails due to the wrong CIDR when
     * {@see $allowSubnet} is set.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string $noSubnetMessage Error message used when validation fails due to {@see $allowSubnet} is used, but
     * the CIDR prefix is not set.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string $hasSubnetMessage Error message used when validation fails due to {@see $allowSubnet} is false, but
     * CIDR prefix is present.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string $notInRangeMessage Error message used when validation fails due to IP address is not allowed by
     * {@see $ranges} check.
     *
     * You may use the following placeholders in the message:
     *
     * - `{attribute}`: the translated label of the attribute being validated.
     * - `{value}`: the value being validated.
     * @param string[] $ranges The IPv4 or IPv6 ranges that are allowed or forbidden.
     *
     * The following preparation tasks are performed:
     *
     * - Recursively substitute aliases (described in {@see $networks}) with their values.
     * - Remove duplicates.
     *
     * When the array is empty or the option not set, all IP addresses are allowed.
     *
     * Otherwise, the rules are checked sequentially until the first match is found. An IP address is forbidden,
     * when it has not matched any of the rules.
     *
     * Example:
     *
     * ```php
     * new Ip(ranges: [
     *     '192.168.10.128'
     *     '!192.168.10.0/24',
     *     'any' // allows any other IP addresses
     * ]);
     * ```
     *
     * In this example, access is allowed for all the IPv4 and IPv6 addresses excluding the `192.168.10.0/24`
     * subnet. IPv4 address `192.168.10.128` is also allowed, because it is listed before the restriction.
     * @param bool|callable|null $skipOnEmpty Whether to skip this rule if the validated value is empty / not passed.
     * See {@see SkipOnEmptyInterface}.
     * @param bool $skipOnError Whether to skip this rule if any of the previous rules gave an error. See
     * {@see SkipOnErrorInterface}.
     * @param Closure|null $when A callable to define a condition for applying the rule. See {@see WhenInterface}.
     *
     * @psalm-param WhenType $when
     *
     * @throws InvalidArgumentException If configuration is wrong.

149		* - Remove duplicates.
150		*
151		* When the array is empty or the option not set, all IP addresses are allowed.
152		*
153		* Otherwise, the rules are checked sequentially until the first match is found. An IP address is forbidden,
154		* when it has not matched any of the rules.
155		*
156		* Example:
157		*
158		* ```php
159		* new Ip(ranges: [

161		* '!192.168.10.0/24',
162		* 'any' // allows any other IP addresses
163		* ]);
164		* ```
165		*
166		* In this example, access is allowed for all the IPv4 and IPv6 addresses excluding the `192.168.10.0/24`
167		* subnet. IPv4 address `192.168.10.128` is also allowed, because it is listed before the restriction.
168		* @param bool\|callable\|null $skipOnEmpty Whether to skip this rule if the validated value is empty / not passed.
