EBSCO Domains for Firewalls, Proxy Servers, and Whitelists

In an effort to provide the best possible response times for your EBSCO subscriptions and services, in July 2016 we are making adjustments to our technical infrastructure. To accomplish this, our services will be delivered from a much larger range of IP addresses and we will no longer be able to provide a list of the IP addresses used by our servers.

This change will only affect those customers who may currently be restricting system access to particular IP addresses – also known as “whitelisting”. For the majority of customers we do not expect this change to have any direct impact, but please consult with your technology department to determine the impact to your organization.

Customers who utilize whitelists will need to change their configurations to utilize domain names instead. An updated list of domains is available below.

Customers who are utilizing domain names may want to take time to review the list below to ensure you have the complete list.

Many of our customers need to allow access through firewalls, proxy servers, caching servers, filtering software and other security features. Below is a list of domains that your network will need to have full access to (incoming and outgoing traffic), in order to use EBSCOhost and our affiliated products to their fullest extent.

To prevent any issues with access, please do not filter or cache the following domains.
