The storagenode itself support the IPv6 from day 0. There are two problems:
- not all customers uses IPv6 (it’s important part, because all data transfers are happening between the node and the customer);
- the Google Cloud still cannot use IPv6 (sic!), thus our satellites, hosted there, cannot communicate via IPv6, but the code itself is allowing to do so.
So the solution at the moment - use dual stack if possible (you would have IPv4 and IPv6). Sooner or later our cloud provider will be able to use IPv6 and this will solve at least one problem.
But using dual stack now will allow your node to accept data via IPv6 from the customers who have a support of it.
