Probably where some of the attitude comes from. People are assuming that it’s paid IT people bringing their work home with them, which is a different case then a casual user trying out self-hosting without the broader background.
Although I haven’t seen this attitude myself so I suspect it’s not that common, and probably just a handful of users jumping to conclusions.
Assuming the Switch supports ipv6, and given how backward Nintendo’s tech tends to be, it wouldn’t surprise me if they didn’t.
Although at least nintendo.com has an AAAA record.
