Is it worth while writing creating a IPv6 stack for embedded systems?

Most people would tell you it's not worth while writing or creating your own IPv4 stack ...
Fianawarrior I'm talking about an IPv6 not IPv4

I think you missed the sarcasm!

Any relevant input?
I'll attempt 
IPv6 is already in some frameworks and RTOS.
8b and 16b MCU in deeply embedded systems can implement standard I/O to a 32b MCU or MPU that has IPv6.

I have friends in the internet business who claim that ipv6 is important and necessary, especially for things like IoT where there are potentially a trillion devices.
Personally, I'm not convinced - the workarounds (NAT, etc) in IPv4 seem to work really well.

Because of NAT I too doubt the need for IPv6.
Think about all your own uses of IP in your house or office? Are you really messing with anything but four part IPV4 addressing? In fact I'd go as far as to say that almost everything you do/configure is probably somewhere under 192.168.x.x
Sure you may set up some DNS servers (probably 8.8.8.8 and 8.8.4.4 in fact!) with a more global IP range but even then it's still IPv4 not v6.
Maybe the Cisco's of this world and the others that provide the "backbone" of the internet concern themselves with IPv6 - but domestic use? Even more so, "embedded micro" domestic use ? I don't think so.

The premise for this argument is that every single "Thing" in the Internet of "Things" needs to have its own, globally-unique, globally-addressable IP address.
Personally, I'm not convinced
Neither am I.
I think the basic premise is flawed.
I don't see the point in being able to directly address every single lightbulb in my from anywhere in the world.
It seems far more sensible that I address my house, and then the things within it are just "sub addresses" of my house - which is what NAT effectively gives us.

More to the point, I see a need to >>prevent<< direct access to every single light bulb from anywhere in the world. Do you trust the light bulb manufacturer to get security right? Or do you do the sensible thing and put it behind a routing/NATting firewall? Will you have a trillion light bulbs behind that firewall?

Fianawarrior Feck it! I think I will implement IPv6. Only problem is finding tools to test and debug development.
Thanks for the input lads.

I think that it is very useful to make systems support ipv6. Not everybody wants to provision ipv4 on every network, it's additional overhead.
While you might think there are enough private ipv4 addresses for anybody's intranet, that doesn't always happen in practice. Company mergers are always interesting, when the companies are using exactly the same address space in their internal networks.
Someone either has to change, or it all just moves to v6.
Also, v6 is more automatic, if you only use link-local scope, or if you have v6 routers, there is no need for (messy, kludgy) dhcp.
Fianawarrior Still thinking about doing an embedded IPv6 stack.

did a brief search in it though was unsuccessful in locating what MCU the ones at Microchip are targeting for Zephyr Project.

Yes, true zephyrs have not been seen in the wild for some generations, and are generally thought to be extinct.

Fianawarrior When I finish my current projects I'll be starting a IPv6 embedded stack.
Bingo600 
While i'm impressed with your ambitions 
I'd say , given your current line of questions here.
A fully working ipv6 stack might be aiming a bit high At the moment.
But best of luck

Ps:
Have a look here

Or if you have the ram (Arm)

Fianawarrior I've already done a IPv4 stack, full implementation DHCP/DNS/ARP/ICMP/UDP/TCP/IP fragmentation.
