How can the AAAA-Record be removed from DNS settings to ensure the server only listens on IPv6 in PHP?
To ensure the server only listens on IPv6 in PHP, the AAAA record can be removed from the DNS settings. This can be done by editing the DNS configuration for the domain and removing the AAAA record associated with the server's IPv6 address. By doing this, the server will only be reachable via IPv6.
// No PHP code is needed to remove the AAAA record from DNS settings.
// This should be done through the domain's DNS configuration settings.
