Hi,
I’m beginner IPv6 technology and try bulid testing enviroment. My ISP have IPv6 address and insiden lan is IPv4 172.16.0.0/24, how can make “nat” IPv4 to public IPv6 address?
That’s not how it works. What you want is to get proper IPv6 subnet and add it to your LAN. Details depend on how exactly your ISP does it, most likely it will be done using DHCPv6. Then you will have so called dual stack, devices with both IPv4 (private) and IPv6 (public) addresses.
