I don't understand. Why would your ISP block your IP for bogus DNS requests? And why are they monitoring your traffic to public DNS servers? I presume this means they have to look at all traffic that goes over port 53. Is there a security concern?
- cydonian_monk 15y agoI have no idea why they would want to block it, unless they considered it an attack vector for some reason. It was automatic - after a few of the bogus DNS requests, all DNS/port 53 traffic was dropped. Everything else worked, only DNS failed.
- brandon 15y agoThis is common practice if the queries appear to be originating from worms like Conficker, etc. Others have reported that this behavior of Chrome's can set off false IDS alarms for the same reason.
