The people who run shodan.io are trying to find workarounds to mitigate that. They were caught a few years ago adding their servers to NTP server pools, and scanning any IPv6 addresses that connected to their NTP server.

- achillean 6y agoAll of the NTP servers had hostnames ending in "shodan.io". The pool account itself was registered using a shodan.io email address. I told the pool operator what we were doing. And I answered anybody who emailed me asking about it (including Brad before he wrote a blog post pretending that he figured it out by himself). At no point were we trying to hide this activity and we made no attempts to do so. I understand that to the end-user this was an unexpected way to discover IPv6 but we really weren't trying to hide it and Brad conveniently didn't mention in his blog post that I told him what we were doing.
- dx87 6y agoIt seems like splitting hairs to say that you didn't try to hide it, but most end-users didn't know that it was being done. It'd be like me recording my neighbors through their window and claiming there is nothing wrong with it because I haven't tried to hide it from them, even though I also didn't let them know I was doing it.
- rovr138 6y agoIsn’t it more recording theater there’s a house at X address? We know the address space already. The approach was for finding used ones.
- achillean 6y agoI don't think that's a good comparison but I doubt we'll agree on it and I'm obviously biased on the matter. I hope the additional context will help readers make their own decision.
