Everyone in Expandi gets their personal dedicated IP address. This is will be done when the customer selects their country of origin. The dedicated IP address is given from that country and is provided by a data center. In case the wrong country is selected, please contact customer support.
You can also select add a custom proxy option while adding a new LinkedIn account or change it to a custom one later on, in the proxies tab under the user menu. Please learn more about it and how to do it here.
If you are not able to see a custom proxy tab on your account, please contact customer support.
