In an otherwise fully IPv6 enabled network, can devices put behind Araknis switches use IPv6? I can't find any mention of IPv6 here: https://www.snapav.com/shop/en/snapav/araknis-switches
Araknis's only current router does support IPv6 (see Specs): https://www.snapav.com/shop/en/snapav/routers/araknis-networks-reg%3B-300-series-dual-wan-gigabit-vpn-router-an-300-rt-4l2w
I'm confused why they'd sell IPv6 routers but not IPv6 switches.
Context: I'm staying at a house with an Araknis router and separate Araknis switch. The router seems to support IPv6 according to its web interface but I can't physically access it to test plugging a device directly into it. But everything behind the switch doesn't seem to pick up an IPv6 address. On SnapAV's website, they don't mention IPv6 support on any of their switches, but their latest routers support IPv6 (mentioned in Specs section).
Update: Thanks for the answers everyone. The router was getting a public IPv6 from the ISP. I got access to the equipment and plugged a device directly into the router rather than the switch, and now it's getting an IPv6 address (though only a fc00::… unique-local address until I enabled prefix delegation on the router, after which it got an additional global address). So, it seems the switch is somehow the problem, despite the theory that it should be ignorant of IPv4 and IPv6. The switch that isn't working for me is an AN-100-SW-R-16 ("Araknis Networks® 100 Series Unmanaged Gigabit Switch with Rear Ports")

A switch doesn't know about IP.
Switches forward Ethernet frames. They don't need to know anything about the protocols at higher layers.
If it is a managed switch it may have a web interface used to configure the switch over IP. Such an interface could support IPv4 or IPv6 or both. However which IP protocol you use to configure the switch doesn't influence what protocols you can use through the switch. You can even send non-IP protocols through a switch.
A managed switch may also have features going beyond switching, some of those features may operate on the IP layer. Some products take this so far that they are actually fully capable routers. Whether a specific device is acting as a switch or a router can depend on how it is configured.
The lack of IPv6 access for hosts connected to the network is unlikely to be caused by the switches, it is more likely caused by the router or the ISP not supporting IPv6.
