- Network Load Balancer now supports listener rules to route traffic to target groups based on source IP address type (IPv4 vs IPv6).
- Enables a single dual‑stack NLB to send IPv4 traffic to IPv4 targets and IPv6 traffic to IPv6 targets while preserving client IPs, eliminating the need for separate load balancers.
- Listener rules work with TCP, UDP, TCP_UDP, and TLS listeners and can be added to existing NLBs without extra charge.
