% host duckduckgo.com
duckduckgo.com has address

Odd, I will CC the CEO.

I think there is no Tor relay running at that IP address currently,
so this exit enclave you're hoping for cannot happen. An exit enclave
is a Tor exit relay that runs on the same IP address as a destination
(e.g. a website).

Perhaps you mean a Tor hidden service, not an exit enclave?

No, I mean a properly configured exit enclave which (as I understand it) is reachable when using Tor without using out-proxies. Out-proxies are the real choke-point of the Tor network...

In which case, yes, if you visit a .onion address, that won't involve
Tor exit relays. You instead do a rendezvous inside the Tor network:

What does 'external validity' mean?
Similarity to the real world and/or applicability outside of the testing environment.  So, would someone in China or Europe get differen circuits, is using the same IP and Tor node over and over going to create caches, etc.
