| Event Type: |
eHealth Exchange Network IP Address Updates |
| Implementer Action Needed: |
Allowlist Updates (if applicable), and self-test and monitor as appropriate |
Description:
The eHealth Exchange network will be implementing updates to the public IP addresses used in our Validation and Production environments. These changes are part of our ongoing infrastructure enhancements to support continued growth, scalability, and reliability across the network.
To minimize participant impact, the changes have been scheduled during a weekend maintenance window when network traffic is at its lowest volume.
We appreciate your cooperation and support as we continue to enhance the scalability and reliability of the eHealth Exchange network.
Details:
As part of this update, inbound and outbound traffic will be assigned separate IP address ranges. In addition, certain environments will expand from a single IP address to multiple IP addresses.
Definitions:
- FQDN (Fully Qualified Domain Name): The complete domain name that uniquely identifies a host or service on a network.
- IPA: IP Address
- INBOUND: The Hub’s public IP address(es) that participant systems use to establish connections and send messages to the eHx Hub. These IP addresses can be determined by performing a DNS lookup on the Hub’s FQDN.
- OUTBOUND: The Hub’s public IP address(es) that serve as the source addresses for requests originating from the eHx Hub. Participant systems will see these IP addresses as the origin of traffic sent by the Hub.
Current State (IP addresses apply to both inbound and outbound traffic):

IMPORTANT ACTION REQUIRED:
Organizations that utilize IP address allowlisting must update their firewall and network security configurations to include the new IP addresses listed above.
Please share this notification with the appropriate network, firewall, and security administrators within your organization to ensure any necessary configuration changes are completed prior to the implementation date.
Failure to update allowlists may result in connectivity issues following the maintenance event.
Scope:
This change applies to the eHealth Exchange Hub Validation and Production environments as outlined above. No changes are being made to the Test environment.
Impact:
The maintenance window is expected to last approximately 60 minutes. During this period, brief service interruptions may occur as the network changes are implemented.
Organizations that maintain inbound and/or outbound IP address allowlists may experience connectivity disruptions if the new IP addresses are not added to their allowlists before the change is completed.
Support:
eHealth Exchange staff will monitor administrator@ehealthexchange.org during the upgrade window to address any questions or concerns.
Additional Information and Reminders:
The eHealth Exchange Hub team has implemented a recurring weekly scheduled maintenance window each Wednesday morning at 10:00am ET for all non-urgent events. The duration of each maintenance event will be determined by the respective changes for each event, and details will be communicated to all Participants at least 48 hours prior to the event. If there are no changes for any given week, then the maintenance event will not occur, and no notice will be sent. Also please note that Operating System and similar updates that do not require a service outage, and do not require changes to the application layer, will be performed during this scheduled maintenance window without specific notice due to their frequent and routine nature.
