CME Public IP Prefix Summary

This list comprises all relevant information regarding subnets advertised to customers on the CME Globex WAN extranet for connectivity to Futures and Options, BrokerTec, and EBS markets. They are in a publicly routable registered address space, but not routed on the Internet, ensuring that customers will not have a conflict taking these routes into their own routing domains.

A port is unique per Order Entry session and per Drop Copy session. Sessions are generated at 4pm CT on the date the session is requested from the CME Request Center NR/Cert and then the port is assigned.

• Futures & Options Requests
