Bind w wersji bind-9.4.1.P1-4 przestał akceptować domyślnie zapytania spoza sieci lokalnej: Allow-query-cache and allow-recursion now default to the builtin acls "localnets" and "localhost". This is being done to make caching servers less attractive as reflective amplifying targets for spoofed traffic. This still leave authoritative servers exposed. Paweł
