Frontier and Verizon have been doing it for years. They have simply thumbed their noses at NXDOMAIN. All in the name of capturing data and eyeballs By Any Means Necessary. -mel On Nov 19, 2019, at 8:00 AM, Matthew Pounsett <matt@conundrum.com> wrote: On Tue, 19 Nov 2019 at 10:57, Patrick Schultz <lists-nanog@schultz.top> wrote: Just to weigh in: Here in Germany, the largest internet provider (Deutsche Telekom) did the same thing. It's basically just a "search guide", it redirects you to a search page and assumes you just had a typo in the URL. Telekom stopped doing that in April, after a user reported them to the district attorney for supposed data manipulation, a misdemeanor. If your entire Internet is just the web then it's perhaps not a big deal. But there are a lot of protocols that depend on proper functioning of NXDOMAIN. If you recall, Verisign got in a bunch of trouble for doing that back in the day at the authoritative level.
