U.S. EPA will be making a change to the IP address for two additional services run by the Central Data Exchange (CDX). This change is in addition to previously announced changes and will impact the services listed in the table below on November 21:
| Hostname | Service Name | Change Date |
| encromerrtest.epacdxnode.net | Shared CROMERR Services | 11/21 after 6PM |
| vestest.epacdxnode.net | Virtual Exchange Services | 11/21 after 6PM |
The new IP address for these services 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. 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.
As a reminder, EPA is also planning the same IP address change to the CDX services listed in the table below. These changes were previously announced and will take place this Friday, November 14.
| Hostname | Service Name | |
| testngn.epacdxnode.net | CDX Next-Generation Node | 11/14 after 6PM ET |
| naas.epacdxnode.net | CDX Network Authentication and Authorization Service | 11/14 after 6PM ET |
| tools.epacdxnode.net | CDX Quality Assurance Tools | 11/14 after 6PM ET |
