Dopo l'attivazione di DoH nel sistema dell'utente, verr\u00e0 visualizzato un avviso che consente di rinunciare al passaggio a DoH e continuare a utilizzare lo schema tradizionale di invio di richieste non crittografate al server DNS del fornitore. \u00c8 possibile modificare il fornitore o disattivare DoH nelle impostazioni della connessione di rete. Oltre ai server DoH di CIRA, si possono scegliere i servizi di Cloudflare e NextDNS.

\"DNS-over-HTTPS<\/center> <\/p>\n

I fornitori di DoH proposti in Firefox vengono selezionati in base ai requisiti per i resolver DNS affidabili, secondo i quali l'operatore DNS pu\u00f2 utilizzare i dati ottenuti per la risoluzione solo per garantire il funzionamento del servizio, non deve conservare i log per pi\u00f9 di 24 ore, non pu\u00f2 trasferire i dati a terzi ed \u00e8 tenuto a rivelare informazioni sulle modalit\u00e0 di trattamento dei dati. Il servizio deve anche assumere l'impegno di non censurare, filtrare, interferire o bloccare il traffico DNS, eccetto in situazioni previste dalla legge. <\/p>\n

Ricordiamo che DoH pu\u00f2 risultare utile per evitare perdite di informazioni sui nomi host richiesti attraverso i server DNS dei provider, combattere attacchi MITM e sostituzione del traffico DNS (ad esempio, quando ci si connette a Wi-Fi pubblici), contrastare le restrizioni a livello di DNS (DoH non pu\u00f2 sostituire VPN<\/a> nell'ambito della elusione delle restrizioni implementate a livello DPI) o per organizzare il funzionamento nel caso in cui non sia possibile accedere direttamente ai server DNS (ad esempio, quando si utilizza un proxy). In situazioni normali, le richieste DNS vengono inviate direttamente ai server DNS configurati nel sistema, mentre con DoH la richiesta di risoluzione Indirizzi IP<\/a> del host \u00e8 incapsulata nel traffico HTTPS e inviata a un server HTTP, dove il resolver elabora le richieste tramite Web API. Lo standard esistente DNSSEC utilizza la crittografia solo per l'autenticazione del client e del server, ma non protegge il traffico da intercettazioni e non garantisce la riservatezza delle richieste.
