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 ftp.yourdomain.com is easier to remember than the generic 1&1 IONOS subdomain of the form homexxxxxxxxxxx.1and1-data.host.

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

Determine server name

First make a note of the name of the 1&1 IONOS FTP server:

Step 1

Use this My 1&1 IONOS login link to go to your Secure FTP access area.

Step 2

Make a note of the server name displayed in the Connection Data section.

Hint: The server name has the form homexxxxxxxxxx.1and1-data.host, for example home12345678.1and1-data.host.

Create FTP subdomain

Now create the subdomain you want to use as an additional server name:

Step 1

Click here to go to your Domains section.

Step 2

In the domain overview, click on the domain for which you want to create your FTP subdomain.

The domain details are displayed.

Step 3

Switch to the Subdomains tab.

Step 4

Under Create subdomain, click Create subdomain.

Step 5

Enter the desired subdomain name and click Save.

The subdomain is created.

Connect FTP subdomain

Finally, you need to connect your new subdomain to the FTP server:

Please note: By following these steps, all other functions of the subdomain (email, website hosting, etc.) will be disabled. We therefore recommend that you use subdomains created exclusively for this purpose.

Step 1

Click on your newly created subdomain in the subdomain overview to display the details.

Step 2

Switch to the DNS tab at the top.

The DNS configuration of the subdomain is displayed.

step 3

Click Add Record.

Step 4

Click CNAME.

Step 5

In the Point to field, type the full name of the 1&1 IONOS FTP server you determined above.

Hint: The field Hostname should already be prefilled with the name part of your subdomain. You can leave the other settings as they are.

Step 6

Click on Save.

Step 7

The system now informs you about the effects of changing the DNS configuration. To agree, click Save again.

The 1&1 IONOS DNS servers are now updated within one hour. You can then use your subdomain as an alternative server name for FTP connections.

Please note: It may take up to 72 hours until the FTP connection via the new subdomain is possible from any Internet connection. For more information, see the article Influences on the Duration of DNS Updates.
