Maintaining IP ranges

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 email online service.

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.


Private IP Ranges are:


  • 10.0.0.0/8 IP addresses: 10.0.0.0 – 10.255.255.255
  • 172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255
  • 192.168.0.0/16 IP addresses: 192.168.0.0 – 192.168.255.255


There are also Multicast IP addresses that are not used to route traffic. The range is:


  • 224.0.0.0 - 239.255.255.255


For more information on Multicast IP addresses, see Multicasting
