The TTL field isn't cryptographically protected though, so it should be very possible that there's an actor after Airtel which does the censoring, no?

- justDankin 6y agoUsing the TTL, we figured out that the censor kicks in at the kth hop. This kth box belonged to Airtel. If a box was censoring after Airtel, we would have received a clean response (ICMP timeout) at hop k as well. Of course, the TTL itself can change during the run, but that wouldn't happen for so many cases :)
- iso1631 6y agoIf you used an allowed domain name, did you get TTL expired messages back when using TTL=5/6/7/8?
- justDankin 6y agoYes, that was the case
