the internet has gone to the dogs

Used to be you could benignly test your dns server with gibberish terms, terms that you knew would return an error.  I used “woof.bark.dog”.  Well, with the current dns system, there are all sorts of top level domains, and it turns out you should not assume there’s nobody there at “.dog”.  These days, there is indeed a bark.dog, and while they don’t have a server named “woof” there will be an answer back.  Not only has the internet gone to the dog(s), there’s .cat, .cricket, .duck.fish, and .jaguar.    So think more carefully the next time you poke DNS to see if you’re running on a live connection – it might jump up and talk back.
