If the IP address of a device is located in a different subnet from the current permanently assigned IP address of the network adapter, a suitable IP address from the subnet of the device is temporarily assigned to the network adapter.
You can display all temporarily assigned addresses and delete them. Note that IP addresses that you manually assigned in the operating system are not displayed in the TIA Portal.
Requirement
To delete, you require adequate permissions.

-
Select the Ethernet interface in the project tree in "Online access".
-
Select the "Properties" command in the shortcut menu of the interface.
The dialog for configuring the interface opens.
-
Select "Configurations > IE-PG access".
A table with the assigned IP addresses is displayed.
-
Click the "Delete project-specific IP addresses" button to delete all the IP addresses at one time.
