I'm not sure if this is well known but you can actually dig (AXFR) the whole .ch and .li zone. Are there other tld that allow this? https://www.switch.ch/open-

  Both .se and .nu also allow it (albeit from a special server, not listed in the NS records for the TLD): https://zonedata.iis.se/ https://zonedata.iis.se/

  yeah .com and many others. You just need to think of some research reason which can be a lot of things, there's no real verification on this, and then you get access to all of the domains at once (you need to be accepted into this central zone dump system once). I was quite surprised when a colleague told me this exists and that he was accepted, since to me this seemed to be coveted data by e.g. commercial dns history companies. Anyhow, if you didn't already --for the myriad of other reasons-- consider DNS data to be open, you should consider it open data.
