Customer is willing to activate IPv6 and dual stack session for subscribers and has below queries:
- What is the method for determining the number of licenses required for IPv6 or dual-stack?
- How to get the number of sessions of a client in IPv6 or dual-stack?
- Regarding a client's bandwidth in dual-stack, does the BNG consider IPv4/IPv6 as a single bandwidth, or does it combine them?
Here are few things for license required
1) scaling license (amount of users)
2) Authentication/address assignment license
3) for pppoe DS (ppp/dhcpv6) the license would consume 2/DS client.
For DHCPv4/DHCPv6 would be the same but there is a feature call single session Dual-stack that you can use. This will be 1 subscriber license used for both.

Other related information as below:
+single session Dual-stack is only for Dhcpv4/Dhcpv6 clients. NOT for pppoe/Dhcpv6
+The scale subscriber license if fine.
+PPPoE is the ifl so the Dhcpv6 will ride on that. So 1 license usages will be used for PPPoE/DS
