IPv6 support on cloudron.io

[girish]

As a prelude to IPv6 support on Cloudron itself, we have added IPv6 support to the Appstore now. https://cloudron.io should now work over IPv6. If anyone hits any connectivity issue, please let us know here.

I was just checking out how realistic it is to have IPv6 only servers. It seems some of the DNS API endpoints like dns.api.gandi.net, api.godaddy.com, api.name.com, api.namecheap.com are IPv4 only. So, Cloudron servers will need IPv4 atleast for a while atleast.

@girish Even if servers have outbound IPv4, they could have inbound IPv6 only (through something like a NAT64)

@mehdi indeed. That is the case on many residential ISPs at least in Germany. The only working solution here is to request a real ipv4 from the ISP, which usually is possible, but likely will cost extra in the foreseeable future.
