Our Domains and IP Addresses

As we continue to keep students and staff members safe on the internet, web and email filters occasionally miscategorize our domains and IP addresses, which can cause availability and access issues for people attempting to engage with the Learning Technology Center.

Fortunately, we are also educators and technology leaders who understand the struggle of constantly finding and re-categorizing important resources for staff and students. To simplify this process, we have created both a simple text-formatted list and a detailed reference table, available on this website.

This list is updated as needed, and we send operational emails to all LTC account holders whenever our subprocessors change. Not an LTC account holder yet? Sign up today.

Incorrectly Categorized Our Website?

If your filtering provider has placed one of our sites in the wrong category, please contact us at support@ltcillinois.org. We'd be happy to work with them to correct the issue for everyone.
