The Global IP Address Database

Experience shows that on average 58% of the IP ranges held by publishers to authenticate libraries who license their content are inaccurate. 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 60,000 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 60,000+ 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

“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”
