#1253 closed enhancement (wontfix)

Identify nodes by hostname to avoid proxy IP blocking

Description (last modified by arma)

Tor use IP addresses for connection to other relays at the moment.
Sometimes all IP addresses is blocked on proxy servers and allowed DNS names only.
It would be good if tor have an option to go by DNS instead of IP.

Yes, this is unfortunately a good way to block Tor. Allowing bridges with
dns names (maybe only when the fp matches?) might be an idea that is
worth exploring.

Description: modified (diff)

I wonder if there are domains that do wildcard dns resolves, where you e.g. ask about a.b.c.d.addresstohost.com and it returns a.b.c.d for you.

Not exactly a foolproof step in the arms race, but still a shuffle forward.

Would this be a good pluggable transport to have around?

Would this be a good feature to add to Tor, along with the IPv6 upgrade?

Yes. I talked to either George or Damian about this topic at the dev meeting in Seattle.

Our pluggable transports need to learn how to survive an http proxy, and this blocking mechanism at the http proxy is orthogonal to (that is, in addition to) whatever brilliant designs the pluggable transports use.

As for whether it would be a good feature to add to Tor, I'd say step zero is to figure out how the feature would work. :)
