What steps can be taken to troubleshoot and address issues with IPv4 and IPv6 address switching on specific web hosting platforms like Strato?

To troubleshoot and address issues with IPv4 and IPv6 address switching on web hosting platforms like Strato, you can start by checking the server configuration settings to ensure that both IPv4 and IPv6 addresses are properly configured and enabled. Additionally, you can try restarting the server or clearing the DNS cache to refresh the IP addresses. If the issue persists, contacting the web hosting provider for further assistance may be necessary.

// Sample PHP code to force the use of IPv4 over IPv6
$context = stream_context_create([
    'socket' => [
        'bindto' => '0.0.0.0:0',
    ],
]);

$handle = fopen('http://example.com', 'r', false, $context);
