Administration - Installation - Core: ILIAS Admin Login - only from a specific network

Is there a plugin or setting in the ILIAS Adminstration, which allows Users with "Admin" role, to login in to ILIAS only from a specific network. i.e. admins are allowed to login to the ILIAS System only from the uni network.

I know such a feature/plugin from Stud.IP, where roots are not allowed to login if they are not in a specific network, is their somthinig simaller in ILIAS?

Thanks in Advance
