How do I update my Institutional IP Address?

IOP Publishing authenticates institutional subscribers by their registered Internet Protocol (IP) addresses. IOP Publishing only accepts IP ranges that belong to the subscribing institution or that the institution uses exclusively. All institutional subscribers must provide their IP addresses or IP ranges within the licence agreement. Library administrators may submit updates or corrections directly through TheIPRegistry.

An IP address is a numerical identifier that identifies each device accessing the internet. It typically consists of four groups of numbers separated by dots (for example, 198.162.123.154). Devices on the same local area network or subnet often share the first two or three number groups.

To ensure the accuracy of usage reporting, IOP Publishing does not permit IP address sharing across multiple institutions or accounts. When an IP address conflicts with one already registered in our system, our Customer Services team contacts both institutions to resolve the issue. Users must not systematically or automatically download content through authorised IP ranges.

All submitted IP addresses are subject to review and approval. We reserve the right to reject any IP ranges that do not meet these criteria. For accurate information, please consult your network administrator.

For a clearer explanation of how IP addresses work and why they matter for access, take a look at our ‘IP Address Glossary’ article. It breaks down the key terms and concepts so you can understand exactly what’s happening behind the scenes.
