This perpetual access level is intended for schools, libraries, and other environments where access is intended to be available on multiple devices within a specific network. After purchasing this subscription type, an IP address or address range, plus the username used to register, will need to be provided to so access can be allowed to users while connected in the institution’s network. After the IP range has been entered in our system, users can access the full content of the site while within the IP address range, with no need for a username and password.
