The full address is still passed along to the services running on top of Tor: for example, an HTTP server may distinguish www.anexampleservice.onion from static.anexampleservice.onion, although Tor will only use "anexampleservice" to route to this server.
Rationale: - not sure "subdomain components" is any clearer (unless it was defined in the recent DNS vocabulary draft) - Tor is not a "layer 3" protocol, moreover you can encapsulate layer 5 sessions, so it's not about "application layers above" either. Introducing OSI layers in this draft would only bring confusion. == hk _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
