I am running a pruned bitcoin node that is running onlynet = onion.
Using the bitcoin-cli I get the list of IP addresses for incoming connections and I can see that there are ipv4 addresses in there. How does that really work? I'm guessing it is a 6 hop circuit because my bitcoin node is a hidden service. If that is the case, then the ipv4 address should not be visible.

I'm sure there is a gap in my understanding for incoming connections and I would really appreciate it if someone could clarify it.
