There's far more than 13 root servers that control the DNS system. Then again
if you would be able to kill all of them it will only mean that DNS servers won't
get updated......but it will still keep on running....and even in the case they
won't then still will all the networks be up and running.......everything will
still be accesible by IP addresses.....The destruction of our planet is the
only thing that will kill the entire internet......good luck
