Creating Your Own FTP Subdomain

If you connect to your web space with an FTP program, you must enter the server name of the 1&1 IONOS FTP server in your program. Alternatively to the generic name of the 1&1 IONOS FTP server, you can also use your own subdomains with your FTP access. We'll show you how.

Advantages of your own FTP subdomain
  • A server name like is easier to remember than the generic 1&1 IONOS subdomain of the form

  • Some FTP programs cannot handle the domain as server name and therefore cannot establish a connection. This can be fixed by using your own subdomain.
