Wolembetsa wa APNIC, yemwe ali ndi udindo wogawa ma adilesi a IP kudera la Asia-Pacific, zotsatira za kusanthula kugawa kwa magalimoto pa imodzi mwa ma seva a DNS a.root-servers.net. 45.80% ya zopempha ku seva ya mizu zinali zokhudzana ndi macheke omwe amachitidwa ndi asakatuli potengera injini ya Chromium. Chifukwa chake, pafupifupi theka lazinthu zamaseva a DNS zimagwiritsidwa ntchito poyesa macheke a Chromium m'malo mokonza zopempha kuchokera ku maseva a DNS kuti adziwe madera. Popeza kuti Chrome imakhala ndi 70% ya msika wasakatuli, zochitika zoterezi zimapangitsa kuti pempho la 60 biliyoni litumizidwe ku ma seva a mizu patsiku.
Macheke amagwiritsidwa ntchito mu Chromium kuti azindikire ngati opereka chithandizo akugwiritsa ntchito ntchito zomwe zimatumiza zopempha ku mayina omwe palibe kwa omwe akuwathandiza. Machitidwe ofanana akugwiritsidwa ntchito ndi ena opereka kuti atsogolere magalimoto ku mayina a mayina omwe adalowetsedwa ndi cholakwika - monga lamulo, kwa madera omwe palibe, masamba akuwonetsedwa ndi chenjezo lolakwika, kupereka mndandanda wa mayina olondola, ndi malonda. Kuphatikiza apo, zochitika zotere zimawononga kwathunthu malingaliro ozindikiritsa omwe ali ndi intranet mu msakatuli.
Mukakonza funso lofufuzira lomwe lalowetsedwa mu bar ya adilesi, ngati liwu limodzi lokha lalowetsedwa popanda madontho, msakatuli woyamba Dziwani mawu operekedwa mu DNS, poganiza kuti wogwiritsa ntchitoyo akuyesera kupeza tsamba la intranet pamanetiweki amkati, m'malo motumiza funso ku injini yosakira. Ngati woperekayo akulozeranso mafunso ku mayina omwe salipo, ogwiritsa ntchito ali ndi vuto - mafunso aliwonse osakira mawu amodzi omwe alowetsedwa mu bar ya adilesi amayamba kutumizidwa kumasamba a wopereka, m'malo motumizidwa ku injini yosakira.
Kuti athetse vutoli, opanga Chromium adawonjezera pa msakatuli , zomwe, ngati zolozeranso zizindikirika, sinthani malingaliro pakukonza zopempha mu bar ya adilesi.
Nthawi iliyonse mukayambitsa, sinthani zoikamo za DNS, kapena kusintha adilesi yanu ya IP, msakatuli amatumiza zopempha zitatu za DNS ndi mayina amtundu woyamba omwe mwina kulibe. Mayinawa akuphatikizapo zilembo za 7 mpaka 15 zachilatini (zopanda madontho) ndipo amagwiritsidwa ntchito kuti azindikire kutumizidwa kwa mayina omwe salipo ndi omwe amapereka kwa omwe akukhala nawo. Ngati, pokonza zopempha zitatu za HTTP ndi mayina mwachisawawa, awiri alandilanso kutsamba lomwelo, ndiye kuti Chromium imawona kuti wogwiritsa ntchitoyo watumizidwa kutsamba lachitatu.
Makulidwe amtundu woyamba (kuchokera ku zilembo 7 mpaka 15) ndi chobwereza bwereza (mayina adapangidwa mwachisawawa nthawi iliyonse ndipo sanabwerezedwe) adagwiritsidwa ntchito ngati zizindikilo zolekanitsa zochitika za Chromium kuchokera pamafunso ambiri pamizu ya DNS seva.
Mu chipikacho, zopempha za madera omwe panalibe zidasefedwa (78.09%), kenako zopempha zomwe zidabwerezedwa zosaposa katatu zidasankhidwa (51.41%), kenako madera okhala ndi zilembo za 7 mpaka 15 adasefedwa (45.80%). . Chochititsa chidwi n'chakuti 21.91% yokha ya zopempha ku ma seva a mizu zinali zokhudzana ndi tanthawuzo la madera omwe alipo.
Kafukufukuyu adawunikanso kudalira kwa katundu wokulirapo pa ma seva a.root-servers.net ndi j.root-servers.net pakukula kutchuka kwa Chrome.
Mu Firefox, DNS imawongolera macheke kufotokoza zolozera kumasamba otsimikizika (otsekeredwa portal) ndi Ρ fixed subdomain "detectportal.firefox.com", osapempha mayina amtundu woyamba. Khalidweli silipanga katundu wowonjezera pa ma seva a DNS, koma akhoza kutero monga kutayikira kwachinsinsi cha adilesi ya IP ya wogwiritsa ntchito (tsamba la "detectportal.firefox.com/success.txt" limafunsidwa nthawi iliyonse ikakhazikitsidwa). Kuti mulepheretse kupanga sikani mu Firefox, pali zoikamo "network.captive-portal-service.enabled", zomwe zingasinthidwe pa tsamba la "about:config".
