Hauv Firefox thiab Chrome feature ntawm kev tshawb nrhiav cov lus nug ntaus hauv qhov chaw nyob bar, uas rau cov ntaub ntawv xa tawm los ntawm tus neeg muab kev pabcuam DNS server. Lub hauv paus ntawm qhov teeb meem yog tias cov lus nug tshawb nrhiav tsuas yog ib lo lus xwb, browser thawj zaug sim txiav txim siab muaj tus tswv tsev nrog lub npe ntawd hauv DNS, ntseeg tias tus neeg siv tab tom sim qhib lub subdomain, thiab tsuas yog tom qab ntawd hloov mus rau lub npe. thov rau lub tshuab tshawb nrhiav. Yog li, tus tswv ntawm DNS server teev nyob rau hauv tus neeg siv cov chaw tau txais cov ntaub ntawv hais txog ib lo lus tshawb nrhiav, uas yog suav tias yog kev ua txhaum ntawm kev ceev ntiag tug.
Qhov teeb meem tshwm sim nws tus kheej thaum siv ob tus neeg muab kev pabcuam DNS thiab "DNS dhau HTTPS" (DoH) cov kev pabcuam, yog tias cov lus qhia DNS tau teev tseg hauv cov chaw (teem los ntawm lub neej ntawd thaum tau txais cov kev txwv ntawm DHCP). Nyob rau tib lub sijhawm, qhov teeb meem tseem ceeb yog tias txawm tias DoH tau qhib, kev thov txuas ntxiv raug xa mus los ntawm tus kws kho mob DNS server tau teev tseg hauv qhov system.
Nws yog ib qho tseem ceeb uas kev daws teeb meem tsuas yog sim thaum xa cov lus nug uas muaj ib lo lus. Yog tias koj qhia ntau lo lus, DNS tsis raug hu.
Qhov teeb meem tau lees paub hauv Firefox thiab Chrome, thiab tseem tuaj yeem cuam tshuam rau lwm tus browsers. Cov neeg tsim tawm Firefox tau pom zoo tias muaj teeb meem thiab muab kev daws teeb meem hauv Firefox 79 tso tawm tshwj xeeb rau kev tswj tus cwj pwm thaum tuav cov lus thov tshawb hauv txog: config "browser.urlbar.dnsResolveSingleWordsAfterSearch", thaum teem rau "0", kev daws teeb meem raug thaiv, "1" (default) siv heuristics rau kev xaiv daws teeb meem, thiab "2" khaws cov cwj pwm qub. Heuristic tshawb xyuas tias DoH tau qhib, tias tsuas muaj 'localhost' nkag rau hauv /etc/hosts, thiab tias tsis muaj subdomain rau tus tswv tsev tam sim no.
Chrome Developers txwv DNS leaks, tab sis ib qho teeb meem zoo sib xws tseem tsis tau daws txij li xyoo 2015. Qhov teeb meem tsis tshwm sim hauv Tor Browser.
