APNIC, munyori anotarisira kugovera IP kero mudunhu reAsia-Pacific, Mhedzisiro yeongororo yekugovera traffic pane imwe yemidzi DNS maseva, a.root-servers.net. 45.80% yemidzi server zvikumbiro zvaive zvine chekuita nekutarisa kwakaitwa neChromium-based browsers. Nekudaro, ingangoita hafu yemudzi weDNS server zviwanikwa zvinoshandiswa kuita Chromium diagnostic cheki, pane kugadzirisa zvikumbiro kubva kuDNS maseva kuona midzi midzi. Tichifunga kuti Chrome inomiririra makumi manomwe muzana emusika wewebhu browser, chiitiko ichi chekuongorora chinoguma mune zvingangoita 60 bhiriyoni zvikumbiro kumidzi maseva pazuva.
Macheki ekuongorora anoshandiswa muChromium kuona kana vapeji vari kushandisa masevhisi anoendesa zvikumbiro zvemazita asiripo kune vanovabata. Vamwe vapeji vanoisa masisitimu akadaro kuti adzore traffic kune asina kupetwa mazita emadomasi. Kazhinji, nzvimbo dzisipo dzinopihwa mapeji yambiro nezve chikanganiso, ichipa runyoro rwemazita angangove echokwadi, uye kushambadzira. Nekudaro, chiitiko chakadaro chinovhiringa zvachose iyo browser intranet host yekuona logic.
Paunenge uchigadzirisa mubvunzo wekutsvaga wakapinda mubhawa rekero, kana izwi rimwe chete risina nguva rakapinda, browser inotanga Ziva izwi muDNS, uchifungidzira kuti mushandisi anogona kunge achiwana intranet saiti pane kutumira chikumbiro kune injini yekutsvaga. Kana ISP ichidzosa zvikumbiro zvemazita asiripo emazita, vashandisi vanosangana nedambudziko: chero-izwi-shoko rekutsvaga mibvunzo yakapinda mubhawa rekero inodzoserwa kumapeji eISP kwete kune injini yekutsvaga.
Kugadzirisa dambudziko, Vagadziri veChromium vakawedzera kune browser , iyo, kana redirection ikaonekwa, shandura iyo logic yekugadzirisa zvikumbiro mubhari yekero.
Pese painotangwa bhurawuza, DNS marongero achinjwa, kana IP kero yachinja, inotumira zvikumbiro zvitatu zveDNS zvine mazita emazita epamusoro-soro anogona kunge asipo. Mazita aya ane mavara manomwe kusvika gumi nemashanu echiLatin (pasina nguva) uye anoshandiswa kuona maISPs achiendesa mazita asiripo emazita kune avo vanovagamuchira. Kana, kana uchigadzirisa zvikumbiro zvitatu zveHTTP nemazita asina kujairika, maviri anotungamirwa kune imwechete peji, Chromium inofunga kuti mushandisi adzoserwa kune rechitatu-bato peji.
Atypical sizes ekutanga-level domains (kubva pa7 kusvika ku15 mavara) uye mubvunzo wekudzokorora chinhu (mazita akagadzirwa zvisina tsarukano nguva imwe neimwe uye haana kudzokororwa) akashandiswa sezviratidzo kusiyanisa Chromium chiitiko kubva mukuyerera kwezvikumbiro pamudzi weDNS server.
Logi yakatanga kusefa zvikumbiro zvenzvimbo dzisipo (78.09%), mibvunzo inodzokororwa isingapfuure katatu (51.41%), uye pakupedzisira madomasi ane mavara manomwe kusvika gumi nemashanu (45.80%). Sezvineiwo, chete 21.91% yemidzi server zvikumbiro zvaive zvine chekuita nekuziva madomasi aripo.
Chidzidzo chacho chakaongororawo kuti kuwedzera kwemutoro pamidzi maseva a.root-servers.net uye j.root-servers.net kunoenderana nekuwedzera kwekufarirwa kweChrome.
DNS redirect cheki muFirefox kutsanangura redirects kune authentication mapeji (captive portal) uye с a fixed subdomain "detectportal.firefox.com," pasina kubvunza mazita epamusoro-level domain. Maitiro aya haagadziri kuwedzera mutoro pamidzi DNS maseva, asi zvinogona kuitika Izvi zvinoburitsa data rakavanzika nezve IP kero yemushandisi (iyo peji "detectportal.firefox.com/success.txt" inokumbirwa pese panotanga Firefox). Kudzima cheki iyi, Firefox inopa marongero anodaidzwa kuti "network.captive-portal-service.enabled," anogona kuchinjwa mu "about:config" peji.
