As a guard node (or someone observing a guard node) trying to locate the
operator of a hidden service, you can use the IP address of the inbound
connection and the Tor directory to see if it's another Tor node or not.
I guess the hidden service operator could use a bridge to create more
ambiguity about what's happening; I don't know for sure if a guard node
has a way to distinguish an inbound connection from a bridge from an
inbound connection directly from a client.
