"The ones that'll continue to make the www outgrow ipv4 and need ipv6 -"
You run the cameras behind your router.....the router firewalls ipv4 and 6 are your choice....I happen to run both.....I can also run he cameras on 2.4 and 5 router bands....they both identify with the cameras to the server web site.
This is part of my problem in understanding "natively support and communicate with products" . I control the router...where there is only one modem connection.
