Azure Bastion support for IPv4 and IPv6 dual-stack
configurations is now available in public preview. Customers can configure a
newly created Bastion deployment with both IPv4 and IPv6 public IP addresses.
IPv6 is supported for connections between the user and Azure
Bastion. Connections from Azure Bastion to target virtual machines continue to
use IPv4. Existing IPv4-only Bastion deployments cannot currently be converted
to dual stack.
