Ingabe amarekhodi e-DNS anegunya angaveza i-IP yasekuqaleni yomsebenzisi we-proxy?
Hlukanisa ikheli lokuphuma kwe-HTTP le-proxy, ikheli lombuzo we-DNS wesixazululi esiphindayo kanye nolwazi olukhethekayo lwe-subnet yeklayenti lapho uhlaziya ukuhlolwa kobumfihlo be-DNS.
Iseva ye-DNS enegunya ivamise ukuthola umbuzo wewebhusayithi kusixazululi esiphindayo. Ngakho-ke i-IP yomthombo kumbhalo wemibuzo wayo ivamise ukukhombisa leso sixazululi, kanti ukuxhumana kwe-HTTP kwewebhusayithi kuvela ku-proxy yangaphambili.
Igama lomsingathi eliyingqayizivele elihlotshaniswa nokuvakasha okukodwa lingahlanganisa umbuzo we-DNS nesicelo sewebhu. Kodwa akushintshi ukuthi imuphi umshini othumela umbuzo ku-seva enegunya ngempela.
Leso sixazululi singase sibe sesomhlinzeki we-inthanethi wovakashile, sesevisi ye-DNS yomphakathi, senethiwekhi ye-proxy noma sesinye isixazululi esidlulisayo. Ukubona ikheli elihlukile kunokuphuma kwe-HTTP kuwubufakazi bendawu yokubheka ehlukile, hhayi ubufakazi obuzenzakalelayo be-IP yasekuqaleni eqondile yovakashile.
Kukhona okuhlukile. Uvakashile angase asebenzise isixazululi esiphindayo yena, futhi i-EDNS Client Subnet ingase iveze ulwazi mayelana nenethiwekhi yeklayenti. Ukunemba kuncike kulokho okuthunyelwa ngempela, kuhlanganise nobude be-prefix; i-subnet ayiyona ngempela ikheli lomsebenzisi oyedwa.
Lapho uhlola ukuhlolwa kobumfihlo be-proxy, bhala okubonakele ngokwahlukene: umthombo we-HTTP, umthombo wombuzo we-DNS kanye nanoma iyiphi idatha ye-subnet yeklayenti. Ukusesha kwendawo okusezingeni lendawo naku-proxy kungashintsha leyo ndlela ye-DNS, kodwa umphumela udinga lokhu kwehlukana ngaphambi kokusekela isimangalo mayelana nobuwena.
