System Documentation

What problem does it solve?

In AWS ECS environments using Service Connect, IPv6 aliases can cause connectivity failures for IPv4-only Fargate tasks because dual-stack DNS returns IPv6 addresses that lack outbound IPv6 routing. This guide documents symptoms, root causes, and practical mitigation strategies to restore reliable service communication.

Core Features & Use Cases

  • Diagnostic workflow for IPv6 dual-stack alias issues in ECS Service Connect, including symptom recognition and root cause analysis.
  • Practical mitigation options: switch to OTLP HTTP, configure IPv4-only DNS records via Cloud Map, or enforce IPv4 on clients.
  • Actionable steps for production environments to prevent recurrence and improve resilience.

Quick Start

Run a diagnostic sequence to identify IPv6/dual-stack DNS issues and apply the recommended mitigation steps.
