CME Public IP Prefix Summary
Overview
This list comprises all relevant information regarding subnets advertised to customers on the CME Globex WAN extranet for connectivity to listed derivatives, 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.
Note: Advertised routes not defined in the list are reserved for future use.
A port is unique per Order Entry session and per Drop Copy session. Sessions are generated at 4 p.m. Central Time on the date the session is requested from the CME Request Center NR/Cert and then the port is assigned.
To generate sessions, refer to:
The Order Entry port details will be available in the CME Request Center NR/CERT from the menu: [market type] Requests > Order Entry Sessions.
The Drop Copy port details will then be available in the CME Request Center NR/CERT from the menu: [market type] Requests > Drop Copy Sessions.
