A Trusted IP address means that an account will be used from only a specified IP address or a list of addresses.
Before withdrawing funds (from an old IP address) add the new IP address to the trusted list. Also, make sure your ISP provides a static, and not a dynamic, IP address.
To set up trusted IPs:
Step 1. Go to “Settings” in your personal account.
Step 2. Select the “Access via IP” tab where you can specify a trusted IP or a list of trusted IP addresses. It will only be possible to use the account from the specified IP address or list of addresses.
Step 3. Specify the desired IP address in the “Add new address” field and click “Save”.
Step 4. After adding the required IP address or addresses, save the settings.
Step 5. Activate the “Enable authorization for trusted IP addresses only” field.
