College IP Addresses

Each college's site IPs are listed above their RA IPs, if applicable. For those colleges who manage their own EZproxy servers, their EZproxy IP address is treated as a site IP in their list of IPs.

Each college who participates in OCLS's Remote Access (RA) service has four RA IP addresses: one production IP that is currently in use by the college and its users, and three backup/testing IPs. The production IP for each college begins with 204.225.107, and ends with the smaller of two possible numbers. (For example, Algonquin's production RA IP address is 204.225.107.40.) Please visit the Remote Access IPs page for more details and to see a list of RA IP addresses only.

If you notice any errors in your college's IP list, or if you have any questions, please contact Nicole Morgan.
