[ipv6-wg] IPv6-only network at RIPE70

I'm glad to announce that there is a IPv6-only (with NAT64) network at RIPE70.

Please note that this experimental network is not supported by the
RIPE NCC or RIPE 67 Technical Team and is offered on a best-effort
basis.

How to connect:

- Make sure IPv6 is enabled on your device
- Connect to SSID: IPV6ONLYEXP
- Enter the password: iknowbesteffort

Please note that NAT64&DNS64 is used to provide connectivity to
IPv4-only resources, so use DNS servers information provided by the
network.

If you see any connectivity issues:
- connect to the 'normal' dual-stack one;
- if connecting to dual-stack network solves the issue, please email
me (furry13 at gmail.com) with details, I'd love to know about any
problems.

General feedback (do you guys see any value in such an experiment,
what was your experience etc) is appreciated.
