L'RFC ha ottenuto lo status di \u00abStandard Proposto\u00bb, dopodich\u00e9 inizier\u00e0 il lavoro per conferire all'RFC lo status di standard bozza (Draft Standard), che significa di fatto la completa stabilizzazione del protocollo e la considerazione di tutti i commenti espressi.<\/p>\n<p>Il meccanismo \u00abDNS Push Notification\u00bb consente al client di ricevere notifiche in modalit\u00e0 asincrona dal server DNS riguardo alle modifiche delle registrazioni DNS, senza la necessit\u00e0 di interrogarle periodicamente. Le notifiche push vengono elaborate solo utilizzando il trasporto TCP con protezione della connessione tramite \u00abTLS over TCP\u00bb. Il server DNS autorevole pu\u00f2 accettare connessioni TCP dai client DNS Push Notification che inviano richieste di iscrizione a nomi e tipi di registrazioni DNS specifici. Dopo aver ricevuto una richiesta di iscrizione, il server invier\u00e0 al client notifiche riguardanti le modifiche alle registrazioni indicate. <\/p>\n<p>Il client determina la presenza del supporto per DNS Push Notification inviando una normale richiesta DNS che verifica l'esistenza della registrazione SRV \u00ab_dns-push-tls._tcp.nome_zona\u00bb, che indica i server DNS che gestiscono le iscrizioni. Il client pu\u00f2 anche iscriversi a una registrazione non esistente, e il server deve avvisare il client se questa appare in futuro. Le notifiche vengono inviate solo in presenza di una connessione TCP stabilita con il server e non sono destinate a monitorare 24 ore su 24, 7 giorni su 7: l'iscrizione deve essere annullata in caso di inattivit\u00e0 (ad esempio, quando il dispositivo passa in modalit\u00e0 standby) e utilizzata solo in caso di necessit\u00e0 diretta di monitorare le modifiche in tempo reale. Attraverso il canale TCP stabilito per le notifiche push possono anche essere inviati normali richieste DSN.<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Fonte: <a \ncontent=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=53276\">opennet.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u0438\u0442\u0435\u0442 IETF (Internet Engineering Task Force), \u0437\u0430\u043d\u0438\u043c\u0430\u044e\u0449\u0438\u0439\u0441\u044f \u0440\u0430\u0437\u0432\u0438\u0442\u0438\u0435\u043c \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u043e\u0432 \u0438 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u044b \u0438\u043d\u0442\u0435\u0440\u043d\u0435\u0442\u0430, \u0437\u0430\u0432\u0435\u0440\u0448\u0438\u043b \u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u0435 RFC \u0434\u043b\u044f \u043c\u0435\u0445\u0430\u043d\u0438\u0437\u043c\u0430 &#171;DNS Push Notifications&#187; \u0438 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b \u0441\u0432\u044f\u0437\u0430\u043d\u043d\u0443\u044e \u0441 \u043d\u0438\u043c \u0441\u043f\u0435\u0446\u0438\u0444\u0438\u043a\u0430\u0446\u0438\u044e \u043f\u043e\u0434 \u0438\u0434\u0435\u043d\u0442\u0438\u0444\u0438\u043a\u0430\u0442\u043e\u0440\u043e\u043c RFC 8765.
