In the coming days, U.S. EPA will be making a change to the IP address for several Central Data Exchange and Exchange Network services. The change will impact the services listed in the table below. Please note that the change will be rolled out in two batches: one on November 4 and another on November 14 as indicated in the table.  

The new IP address will be 204.47.255.182. EPA expects this change to be transparent to all users except for organizations who use firewall rules to restrict outbound traffic in server environments. Node administrators in those environments should be aware that firewall rules will need to be implemented at the nearest opportunity allowing the new IP address (204.47.255.182) to avoid service disruptions.

For more information or answers to questions, please contact the Exchange Network Help Desk at 1-(888)-890-1995 or [email protected].
