This list comprises all relevant information regarding subnets advertised to customers on the CME Globex WAN extranet for connectivity to Futures and Options and BrokerTec 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.

To generate sessions, refer to: 

The Order Entry port details will be available in the CME Request Center NR/CERT under either:

  • Futures & Options Requests >Order Entry Sessions
  • BrokerTec Requests>Order Entry Sessions

The Drop Copy port details will then be available in the CME Request Center NR/CERT under either:

  • Futures & Options Requests>Drop Copy Sessions
  • BrokerTec Requests >Drop Copy Sessions
