Cloud Load Balancing: Reserve BYOIP IPv6 Addresses
Cloud Load Balancing now allows reserving specific or auto-allocated bring-your-own-IP (BYOIP) IPv6 addresses for regional external passthrough Network Load Balancers. This feature ensures IPv6 addresses persist independently of the load balancer's lifecycle and allows promoting ephemeral BYOIP addresses to reserved static ones. The capability is currently in Preview, impacting engineers and architects managing network infrastructure.
