Unable to changing an IP address for a domain in Plesk via CLI: it is already used by another account.

Symptoms

• When changing an IP address for a domain via a command-line interface, the operation fails with:

  # plesk bin subscription -u example.com -ip 203.0.113.2

  Unable to set IP address 203.0.113.2 for hosting: it is already used by another account.

• Cannot change owner of the subscription:

  # plesk bin subscription --change-owner "example.com" -owner "JoeDoe"
  Some problems were encountered when attempting to assign some of the subscriptions to a new owner.
  Unable to continue subscription transfer: IP pool of the new owner's provider is empty. Please make sure that the provider has at least one IP address in the pool.

• The IP address (in this example, 203.0.113.2) has the type 'dedicated' at Tools & Settings > IP Addresses.

• The subscription belongs to a reseller or a reseller's customer.

• The corresponding reseller does not have this IP address at Resellers > John Doe > IP Addresses.

Cause

The IP address has not been added to the reseller's IP address pool.

2. Go to Resellers > John Doe > IP Addresses.

   

3. Click the Add IP Address.
