On July 28 2025, starting at 08:00 UTC, we will enable dual-stack connectivity for our GovCloud (FedRamp Moderate) infrastructure. This means that both IPv4 and IPv6 addresses will be supported for connections to your Elastic services in GovCloud (FedRamp Moderate).
More specifically we will enable dual stack configuration on the Load Balancer that handles connections to GovCloud Endpoints. Essentially this means that DNS for hostnames like mydeployment.kb.us-gov-east-1.aws.elastic-cloud.com or mydeployment.es.us-gov-east-1.aws.elastic-cloud.com will start resolving to both IPv4 (A records) as well as IPv6 (AAAA records). Then any connections towards the deployment, to Elasticsearch, Kibana, Integrations Server, APM, etc will be either on IPv4 or IPv6 depending the IP configuration on your side.
If you operate in a firewalled environment or if you employ Elastic Traffic filters you must update your rule set for IPv6.
