Go to the Access page on the Librarian Portal for a full list of the IP ranges from which your licensed content can be accessed.
If you wish to make any changes to these ranges, please submit a ticket to our Online Service teams with the relevant information or send an email to: email@example.com.
Please note we do not permit private or intranet IP addresses to be associated with a customer account. They are private and not discoverable in the public internet space so would not enable access as a user would never reach our sites via a private IP. The IP address you will see on your personal computer will be your private IP, but if you go to a site like whatismyipaddress.com you will see a different IP which is your public IP.
For more information please see Private IP Addresses: Everything You Need to Know.
