Many of my sites/projects are dual homed on IPv4/IPv6
I'm fully IPv6 capable here. I'd like to see an IPv6 strategy rolled out. I have a /56, so it would be dead easy to dedicate a /64 to ham radio projects. I'd probably have to build the internal router for that subnet, so I can more functionality for routing and access control.
While both my node software and my servers are all dual stacked as well, the issue with using IPv6 on RADIO (UHF/VHF/HF) is a bit of a challenge but do-able.
We've rolled out IPv6 on many eastnet sites with pretty good success however the means of which to transport IPv6 under ax.25 is where the challenge is. If you study how the routing is configured under ax.25, ARP is required - yet in IPv6 ARP is eliminated. To roll out a 100% successful IPv6 environment on RADIO with the exception of 802.11, IPv4 is still required.

I have a /48 which I broker out to the EastNet FlexNet nodes. While it does work at 1200 baud, because of the IPv4 layer adding overhead it's not necessarily preferred. I haven't tested it on HF and don't really intend to as I would think under poor conditions it may be too difficult to pass the entire protocol layers, even though I've passed IPv4 on HF fine.
