This is something I’ve felt we’ve needed for a long time, but cloudscalers have their own environments that include resource management and beyond dev, if anything goes wrong they either reboot the net image or offline it for maintenance.
This is something I’ve wanted to throw together, will give it a try soon, could even be useful for development.
Used to have miredo, which worked pretty well, but think they killed that.
Should still have old 6to4 protocols, they use ipv4 address tricks to get everything working.
