Request Authentication Information

Current and potential electronic resource vendors may submit a request for the current ranges used for authenticating access to electronic resources at vendor platforms by sending an email to cdl@www.cdlib.org. CDL does not provide lists publicly or for other uses.

The IP address list changes as campuses add new IPs and re-assign existing ones. The list includes IP addresses specifically authorized for electronic resource access for the 10 UC campuses, UC Office of the President (UCOP), and the Ernest Orlando Lawrence Berkeley National Laboratory (LBL). The UCOP addresses include the California Digital Library IP addresses necessary to enable CDL staff to troubleshoot problems, view and evaluate the resources, and respond to feedback about these resources that the CDL receives.
