The case - then, for example, attempts to block Telegram servers lead to unexpected unblocking some forbidden sites, like kasparov.ru - shows how some networking skills can be grown en masse in a short period of time.

So, yes, average Internet user isn't very familiar with DNS. Maybe privacy wars will lead to growing awareness in this area though.
