ICANNpolicies for Assigning Dedicated IP Addresses to Subdomains

ICANN requires that a website owner meet one of 2 simple requirements before dedicating an IP address to his or her domain. The user’s domain or subdomain must either:

* Require an SSL Certificate — Generally, these certificates are used for e-commerce. SSL Certificates ensure visitors that they are sharing sensitive information on a secure connection with the appropriate domain.
* Run an anonymous FTP site.

Assigning a dedicated IP address for any other reason than the reasons listed above is a violation of ICANN’s terms.

Prevent subdomains and domain aliases in the DNS zones belonging to other users in Plesk.

By default, users can create new subdomains and domain aliases in the DNS zones belonging to other users. This means that they can set up Web sites and e-mail accounts which could be used for spamming, fishing or identity theft.

To prevent users from setting up domains and domain aliases in the DNS zones belonging to other users:

1. Go to Settings > Restrict Creation of Subzones (in the DNS group).
2. Select the Do not let users create DNS subzones in other users’ DNS superzones check box.
3. Click OK.
