Solo gli utenti le cui attuali impostazioni di sistema specificano alcuni fornitori DNS ritenuti compatibili con DoH parteciperanno all'esperimento di attivazione di DoH. <\/p>\n

Nell'elenco dei fornitori DNS abilitati ci sono servizi<\/a><\/noindex> Google (8.8.8.8, 8.8.4.4), Cloudflare (1.1.1.1, 1.0.0.1), OpenDNS (208.67.222.222, 208.67.220.220), Quad9 (9.9.9.9, 149.112.112.112), Cleanbrowsing (185.228.168.168, 185.228.169.168) e DNS.SB (185.222.222.222, 185.184.222.222). Se nelle impostazioni DNS dell'utente sar\u00e0 specificato uno dei server DNS sopra menzionati, DoH in Chrome sar\u00e0 attivato per default. Per coloro che utilizzano i server DNS forniti dal fornitore di servizi internet locale, tutto rimarr\u00e0 invariato e per le query DNS continuer\u00e0 a essere utilizzato il risolutore di sistema. <\/p>\n

Una differenza importante rispetto all'implementazione di DoH in Firefox, in cui l'attivazione graduale di DoH per default inizier\u00e0<\/a><\/noindex> gi\u00e0 alla fine di settembre, \u00e8 l'assenza di un legame con un servizio DoH. Se in Firefox per impostazione predefinita viene utilizzato<\/a><\/noindex> il server DNS di CloudFlare, in Chrome verr\u00e0 semplicemente aggiornato il metodo di lavoro con DNS a un servizio equivalente, senza cambiare fornitore DNS. Ad esempio, se un utente ha impostato 8.8.8.8 nelle impostazioni di sistema, in Chrome ci sar\u00e0 attivato<\/a><\/noindex> DoH-\u0441\u0435\u0440\u0432\u0438\u0441 Google («https:\/\/dns.google.com\/dns-query»), \u0435\u0441\u043b\u0438 DNS — 1.1.1.1, \u0442\u043e DoH \u0441\u0435\u0440\u0432\u0438\u0441 Cloudflare («https:\/\/cloudflare-dns.com\/dns-query») \u0438 ecc.<\/a><\/noindex><\/p>\n

L'esperimento per abilitare DoH sar\u00e0 condotto su tutte le piattaforme supportate da Chrome, ad eccezione di Linux e iOS a causa della complessit\u00e0 nell'analisi delle impostazioni del resolver e delle limitazioni di accesso alle impostazioni DNS di sistema. Se dopo l'attivazione di DoH si verificano problemi nell'invio delle richieste al server DoH (ad esempio, a causa del suo blocco, di problemi di connettivit\u00e0 o guasti), il browser ripristiner\u00e0 automaticamente le impostazioni DNS di sistema. <\/p>\n

L'obiettivo dell'esperimento \u00e8 la verifica finale dell'implementazione di DoH e l'analisi dell'impatto dell'uso di DoH sulle prestazioni. Si noti che il supporto di DoH \u00e8 stato effettivamente integrato aggiunta<\/a><\/noindex> nel codice sorgente di Chrome gi\u00e0 a febbraio, ma per configurare e abilitare DoH era necessario<\/a><\/noindex> avviare Chrome con un flag speciale e un insieme non evidente di opzioni.<\/p>\n

Ricordiamo che il DoH pu\u00f2 risultare utile per evitare perdite di dati sui nomi host richiesti attraverso i server DNS dei provider, per contrastare gli attacchi MITM e la manipolazione del traffico DNS (ad esempio, quando ci si connette a Wi-Fi pubblici), per affrontare i blocchi a livello di DNS (il DoH non pu\u00f2 sostituire una VPN per eludere i blocchi implementati a livello di DPI) o per garantire il funzionamento in caso di impossibilit\u00e0 di connettersi direttamente ai server DNS (ad esempio, quando si lavora tramite un proxy). Se normalmente le richieste DNS vengono inviate direttamente a determinati server DNS configurati nel sistema, nel caso del DoH la richiesta di risoluzione dell'indirizzo IP dell'host viene incapsulata nel traffico HTTPS e inviata a un server HTTP, dove il resolver gestisce le richieste tramite un'API Web. Lo standard esistente DNSSEC utilizza la crittografia solo per l'autenticazione del cliente e del server, ma non protegge il traffico dall'intercettazione e non garantisce la riservatezza delle richieste. <\/p>\n
