IP Version should not interfere with C5. C5 must be accessible from the network. The server you use is the one who should be able to map IP Addresses to C5 Folder.


That said, if you want a longer explanation about IPv6:

IPv6 is the "Evolution" of the IP protocol.

It means we get bazillion new options for addresses and things get more "Automated".

Also, it means speed. From 100Mbps to 1000Mbps.


Now, considering Internet providers didn't even get to the 50Mbps, you most likely don't have to worry about that. The internet is IPv4. Even if you have a host with everything working with IPv6, when someone accesses from the Internet they'll be limited for the IPv4 protocol, so for quite a few years, there will be not much of a change.

Even when it changes, it will be like when the broadband appeared for the users. Not that much of a difference on the server side, at the beginning, since it was slowly getting faster, bit by bit.
Source is me. I work with IT Infrastructure and did lots of things with Gigabit Ethernet. IPv6 is the protocol to navigate on Gigabit Ethernet (1Gbps or 1000Mbps).
