Force IPv6 only Wifi from Raspberry

Thu Jun 30, 2016 5:38 pm

Hi,

Could someone please guide me how to setup Raspberry Wifi to provide IPv6 address only?

I am using Raspberry Pi 3 with below OS details.

uname -a
Linux raspberrypi 4.1.18-v7+ #846 SMP Thu Feb 25 14:22:53 GMT 2016 armv7l GNU/Linux

Please let me know if more details needed.

Reagrds,
Sachin

It would be a bit complicated to do, but can be done. What is the mfg and model of the Router/Gateway that you are using on your network?

You would have to set the Network connection to use IPv6 "Link local only". You would also need a dual stack router if you do not plan on placing the devices behind a machine running pfSense to handle that group. See the following links. There are more out there if you do a search for "debian jessie lan ipv6 only".

Hi,

switch off Ipv4 and you have ipv6 only ;)

Things you should consider:

Do you have native IPv6?
Can you split a /64-subnet from your /56 or /48?
Has your router static assigned addresses or dynamically assigned addresses?
The first case is easier. The last case would require dhcpv6-prefix-delegation.
Do you have already a DNS64/NAT64-gateway in your network? If not, would you use an external (public) DNS64/NAT64-provider?

Are you familiar with radvd (RA + DNS) and dhcpv6?

Good luck!
