% host duckduckgo.com
duckduckgo.com has address

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?

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?
