IP Address 

The IP trigger is used to show the indicators in the TYPO3 backend for specific IP addresses.

ext_localconf.php 
\KonradMichalik\Typo3EnvironmentIndicator\Configuration\Handler::addIndicator(
    triggers: [
        new \KonradMichalik\Typo3EnvironmentIndicator\Configuration\Trigger\Ip('127.0.0.1', '192.168.0.0/24')
    ],
    indicators: [
        new \KonradMichalik\Typo3EnvironmentIndicator\Configuration\Indicator\Backend\Topbar([
            'color' => '#00ACC1',
        ]),
    ]
);

The configuration supports multiple IP addresses as separate arguments. Both IPv4 and IPv6 addresses are supported. CIDR range notation is also supported for both address families (e.g. 192.168.0.0/24 or 2001:db8::/32). Invalid IP formats will throw an InvalidArgumentException during construction.
