The Global IP Address Database for Libraries and Publishers

Experience shows that up to 13% of IP addresses manually input into publishers’ authentication systems are likely to be inaccurate. Historically, when PSI has cleaned IP address data for publishers up to 40% of IP addresses have been removed as they are either out-of-date or incorrectly allocated. Apart from unlicensed access, a consequence of incorrect IPs can be inaccurate usage statistics for both publishers and libraries.

Until now, the systems for keeping the IP ranges accurate and up to date were cumbersome, time-consuming and inefficient for both publishers and libraries.

The IP Registry is a single repository of the validated IP addresses for over 70,000 content licensing organisations worldwide, accessible by both publishers and libraries and maintained for the benefit of the whole scholarly communication community by PSI based in Oxford, UK and Boston, USA.

How it works

Register your organisation and receive your admin login. Check and update (if necessary) the IP ranges held. Add your organisation if it is not one of the 70,000+ currently in the database.

Updates and additions are checked, validated and made live in the Registry.

Publishers harvest the validated ranges manually or via our API for inclusion in their access management systems.

No more unlicensed access

“I believe it’s a valuable service and I hope that more content providers will keep track of IP changes through here. Just this week I’m auditing our IP addresses with a major aggregator, and their list of our IP addresses is a mess. If they subscribed to the IP Registry, they, their customers, and the accuracy of their customers’ usage data would all benefit greatly.”

“The University of Cambridge warmly supports the IP Registry initiative and looks forward to the greater efficiencies it will bring, not least in reducing the admin overhead with multiple publishers and in ensuring reliability for our usage statistics data”

“I’ve been following this project for a few years and think it was a stroke of genius. It will save a lot of time on my end for sure.”

“I would like to say that the idea where libraries will give their essential data to publishers in only one place is great!”

“It makes me very happy when I receive an email saying that one of our vendors has joined theIPregistry.org. It makes managing our IP addresses so much easier.  Thank you!!”
