Yes, of course. I apologize for being unclear. I meant - what in the
internal workings of the node makes it hidden or not? What preventa a C node
from looking like a normal one? I suppose it's all in the protocol, but am
not sure.

Ah, okay now I get it. I thought it would change the cookie for a node one
is already connected to.

Thanks!
