I’m not too familiar with VPNs that offer IPv6 addresses, so I can’t help with that. But I’m curious about why some people want IPv6 addresses. Are there any benefits to having an IPv6 address?

What benefit does this have over a Zigbee dongle on Amazon that’s cheaper? Would the advantage be that this is a 3-in-1 dongle?

Depends on the community. I’ve met some very helpful noob-friendly developers who recognize you’re a noob and will use simpler terms to guide you through the process, and passive aggressive assholes that’ll ignore your messages the very second they figure out you’re a noob. Even though they were literally just talking to you seconds before.
