Routes

Update

Custom routes now support Gateway Load Balancer (GWLB) as the next hop.

Update

You can modify the next hop of custom route entries to dynamically manage network traffic.

VPC

Update

You can configure private domain name resolution for Elastic Compute Service (ECS) instances in VPCs. The private domain names of ECS instances are only effective when DNS hostnames are enabled for the VPC. If DNS hostnames are disabled, the private domain names will become inactive.

Flow logs

Update

You can configure the traffic to be captured for specific scenarios. The available options include All Traffic, Traffic Through IPv4 Gateway, Traffic Through NAT Gateway, Traffic Through VPN Gateway, Traffic Through Transit Router, Traffic That Accesses Cloud Service Through Gateway Endpoint, and Traffic That Accesses Express Connect Circuit Through Virtual Border Router (VBR).

IPAM

Update

Resource discovery is automatically enabled and associated with the IPAM when you create an IPAM. You can use it to manage the IP addresses of VPCs and vSwitches.

Update

You can monitor IP address usage to manage capacity and scale out resources as needed. This helps to ensure network stability and security.

Update

The resource owner of an IPAM pool can share the pool with other Alibaba Cloud accounts, known as principals. Principals can allocate resources from the shared IPAM pool when creating a VPC.

Routes

Update

A VPC can advertise static routes to an Express Connect Router (ECR). You can advertise a custom route of a VPC system route table to an ECR to implement dynamic route advertisement. If no route conflicts occur, the data center associated with the ECR can learn the route.
