 ### How small and how large can VNets and subnets be?
-The smallest supported subnet is /29, and the largest is /8 (using CIDR subnet definitions).
+The smallest supported IPv4 subnet is /29, and the largest is /8 (using CIDR subnet definitions).  IPv6 subnets must be exactly /64 in size.  
 
 ### Can I bring my VLANs to Azure using VNets?
 No. VNets are Layer-3 overlays. Azure does not support any Layer-2 semantics.

 Yes. All services deployed within a VNet can connect outbound to the internet. To learn more about outbound internet connections in Azure, see [Outbound connections](../load-balancer/load-balancer-outbound-connections.md?toc=%2fazure%2fvirtual-network%2ftoc.json). If you want to connect inbound to a resource deployed through Resource Manager, the resource must have a public IP address assigned to it. To learn more about public IP addresses, see [Public IP addresses](virtual-network-public-ip-address.md). Every Azure Cloud Service deployed in Azure has a publicly addressable VIP assigned to it. You define input endpoints for PaaS roles and endpoints for virtual machines to enable these services to accept connections from the internet.
 
 ### Do VNets support IPv6?
-No. You cannot use IPv6 with VNets at this time. You can however, assign IPv6 addresses to Azure load balancers to load balance virtual machines. For details, see [Overview of IPv6 for Azure Load Balancer](../load-balancer/load-balancer-ipv6-overview.md?toc=%2fazure%2fvirtual-network%2ftoc.json).
+Yes, VNets can be IPv4-only or dual stack (IPv4+IPv6).  For details, see [Overview of IPv6 for Azure Virtual Networks](./ipv6-overview.md).
 
 ### Can a VNet span regions?
 No. A VNet is limited to a single region. A virtual network does, however, span availability zones. To learn more about availability zones, see [Availability zones overview](../availability-zones/az-overview.md?toc=%2fazure%2fvirtual-network%2ftoc.json). You can connect virtual networks in different regions with virtual network peering. For details, see [Virtual network peering overview](virtual-network-peering-overview.md)
