When IP addresses are incorrect, content is opened up to the wrong customers without payment and without publishers' knowledge. Libraries could be charged more than they should be for resources, based on inflated usage metrics, and could be making renewal decisions based on usage coming from outside their organisation. It benefits all parties to ensure that publishers are using the right IP addresses.

Publishers can hold the wrong IPs for various reasons:

  • Publisher staff enter details incorrectly

  • Library staff provide incorrect details to publishers

  • IPs are deliberately added to accounts in order to hi-jack access

  • Old IPs are left active on the original account is the only service that checks and verifies IP addresses to eliminate this kind of error.
