I didn’t ask what kind of “gimmicks” are possible with IPv6 and what IPv6 brings for you, others, the provider or the world, but rather what measurable, concrete, immediately noticeable advantages for me personally IPv6 has now and today My technically very modest household would benefit if I were to tick the v6 box on the PC and the IB today?
I have asked this question over the last 20 years with countless top experts (first in 2002 with Ms. Silvia Hagen, author of several specialist books and founder of the IPv6 Forum), professors from various universities and top ICT experts from leading manufacturers of network equipment (including Cisco and HP) discussed. The answers were always more or less identical and have long been known to me: address scarcity, security, elimination of NAT/multiple NAT, integrated QoS, more efficient routing, advantages with VPN and direct E2E connections, elimination of the DHCP server thanks to SLAAC, easier implementation global transparent addressing concepts, and, and, and.
Everything is good, right, correct and, on the whole, absolutely necessary. long overdue. But it doesn’t even begin to answer my question above.
