Rage4 DNS - setting up IPv4/IPv6 translation

I remembered in Cloudflare there is such a feature that if your VPS is IPv6 only, Cloudflare would be able to make it visible to IPv4 by sort of "translating" the request to the IPv6 space. I recall that Rage4 has something similar to this but I could not remember where it is or how to enable it.

Anyone has any tip for me?

    rage4 isn't a cdn, so no

  • Rage4 is only DNS, they don't do any layer 7 proxying like cloudflare does.

    It's relatively easy to do this with nginx and any IPv6 enabled VPS, although it will cost you something

    how does cdn relate to ipv6 -> ipv4?

    Problem solved, that was quick, thanks people, looks like it still needs to go through Cloudflare then.

    The reason CF can do this is because they proxy web connections to your web server, so when a user visits your domain the user hits their content network, which goes back and fetches your pages (or serves them from cache, depending on lots of factors). They can fetch your page over v6 and serve them over v4 just as easily as they can fetch them over v4, which creates a little v4 -> v6 proxy.

    Something like DNS doesn't do any of this, it's like a little phone book and nothing more.

    ah okay, got it. Thanks for the explanation :)

    you can install a nginx on a vps for a 6to4 reverse proxy, if your vps doesn't have a ipv6, you can set HE's free ipv6 on your vps to achieve the transiting

    Right, as mentioned above, Cloudflare does this as part of their CDN, but technically a non-caching reverse proxy could work too.

    I meant the other way round, specifically if your VPS is IPv6 only how do you make sure the sites shows up on the V4 side of the world.

    Don't you need a plain IPv4 for it?

    Nope.

    With CloudFlare, you just set an AAAA record at the domains you're serving and they'll handle it. If you don't use CF, you'll need a machine accessible on v4 to do 4->6 with any reverse proxy like nginx.

    That's what I did, thanks!
