When you create an IONOS subdomain, it automatically creates an FTP A record. This A record points to the current IONOS FTP server. They eventually upgrade their FTP server, but leave the old FTP server online forever. Their billing system scans DNS records and sees that a domain/subdomain is pointed to the old IONOS server with PHP 5.5 running. They then automatically start billing the client monthly for PHP 5.5 extended support. 6 years my client has been paying for this. What a great revenue scam.
