  • You can run into this issue with any two sync programs that operate on virtual files, as another commenter said. This isn’t specifically a OneDrive or NextCloud problem. You can safely run both at the same time on the same machine, as long as they are syncing entirely separate directories.

    That being said, this is obscure enough that I feel like there should be some kind of check in these clients to make sure they’re not about to interfere with each other - users aren’t gonna know to check for this, especially since these clients are hiding what they’re actually doing behind the scenes!

    MAC addresses are link-local device identifiers, used by the switches and routers and WiFi access points that talk directly to the devices in question. Switches and routers maintain a table of which MAC to send a packet to based on the IP address - I.e. which actual port to send the data frames down.

    There is DHCP for IPv6, but the IPv6 stack is supposed to be able to detect which subnet it’s router is in and then just pick addresses on its own (it does look for conflicts before committing to an address). This is called SLACC (stateless address auto configuration).

    NAT is unnecessary because there are so many addresses, as others have mentioned; but I did want to point out that NAT is not used for security. Just because it obscures your devices does not make them any safer. All IPS routers have a firewall to one degree or another (could be as simple as “no incoming connections”; which is bad and lazy but it happens). Firewalling - examining incoming traffic against a set of rules for allowing or denying - is the correct way to secure any network, IPv4 or IPv6.
