Restricting administrator access to specific IP addresses is a critical security measure in Plesk. By limiting which IP addresses can log in to the administrator account, you prevent unauthorized access even if login credentials are compromised, making remote server hacking significantly more difficult.
How to Restrict IP Addresses
-
Step 1: Access IP Access Restriction Management
Log in to your Plesk administrator account. Navigate to the side menu and choose Tools & Settings. Under the Security section, click on IP Access Restriction Management.
-
Step 2: Configure Access Policy
Select the Settings option.
Choose one of the following options:
- Allowed, excluding the networks in the list: This prevents login from the listed IP addresses for the Administrator or Additional Plesk Administrator.
- Denied from the networks that are not listed: Only the specified IP addresses in the list will have authorization to log in as Plesk Administrator or Additional Plesk Administrator.
Click OK.

Step 3: Add Restricted IP Addresses
Select Add Network to include a new restricted IP address.
Input the Subnet or IP address to append to the list of restricted IP addresses and then click OK.
