Our Domains and IP Addresses
As we continue to keep students and staff members safe on the internet, web and email filters occasionally mis-categorize our domains and IP addresses which can cause availability and access issues for people attempting to engage with the Learning Technology Center.
Fortunately, we have a lot of amazing educators and technology leaders who understand the struggle of constantly finding and re-categorizing important resources for our staff and students. In the effort of simplicity, we have created a simple list in addition to this website, which explains which domains are used for which purpose. The list is updated when necessary, and we send operational emails to all people with LTC accounts when our subprocessors change. Not an LTC account holder yet? Sign up here.
Notice an issue with your filtering provider putting our site in the wrong category?
Please reach out at support@ltcillinois.org and let us know! We'd love to work with them and correct it for everyone.
