Kuhle ntambama
Abasebenzisi abaningi, ikakhulukazi labo abasebenzisa ikhompyutha okokuqala, baye bazwa ngesifingqo se-DNS okungenani kanye (kulokhu akulona isitolo sekhompyutha hardware :)).
Ngakho-ke, uma kunezinkinga nge-Intanethi (isibonelo, amakhasi e-intanethi avulwa isikhathi eside), labo abasebenzisi abanolwazi oluningi, bathi: "inkinga cishe ihlobene ne-DNS, zama ukushintshela ku-DNS 8.8.8.8 ye-Google ..." . Ngokuvamile, ngemva kwalokhu kuvela ukungezwani okukhulu nakakhulu ...
Kulesi sihloko ngifuna ukuhlala ngalolu daba ngokuningiliziwe, futhi ngihlaziye izinkinga eziyisisekelo ezihlobene nalesi sitfombe. Futhi kanjalo ...
DNS 8.8.8.8 - yini futhi kungani kuyadingeka?
Ukunakwa, okuqhubekayo kulesi sihloko, amanye amagama ashintshwe ukuze kube lula ukuqonda ...
Zonke izingosi ozivulela kusiphequluli zigcinwa ngokomzimba kunoma iyiphi ikhompyutha (ebizwa ngokuthi iseva) enekheli layo le-IP. Kodwa uma ufinyelela isayithi, asifaki ikheli le-IP, kodwa igama elithile elithile lesizinda (isibonelo, Ngakho-ke ikhompyutha ithola kanjani ikheli le-IP elifunayo le-server elithinta isayithi esivulayo?
Kulula: ngenxa ye-DNS, isiphequluli sithola ulwazi ngokuhambisana kwegama lesizinda nekheli le-IP. Ngakho, okuningi kuxhomeke kuseva ye-DNS, isibonelo, ijubane lokulayisha amakhasi wewebhu. Ukuthembeka futhi okusheshayo iseva ye-DNS, umsebenzi wakho wekhompiyutha ngokushesha futhi okhululekile kwi-inthanethi.
Kuthiwani ngomhlinzeki we-DNS?
Umhlinzeki we-DNS ongazifinyelela ku-Intanethi akuyona esheshayo futhi enokwethenjelwa njenge-Google DNS (ngisho nabahlinzeki be-intanethi abakhulu benza isono ngamaseva abo e-DNS, bangabi namancane amancane). Ngaphezu kwalokho, ijubane labaningi lishiya kakhulu.
I-Google Public DNS inikeza amakheli esiphakeli omphakathi alandelayo kumbuzo we-DNS:
- 8.8.8.8
- 8.8.4.4
-
I-Google ixwayisa ngokuthi i-DNS yayo izosetshenziselwa kuphela ukusheshisa ukulayisha ikhasi. Amakheli we-IP wabasebenzisi azogcinwa ku-database ngamahora angu-48 kuphela, inkampani ngeke igcine idatha yomuntu siqu noma kuphi (isibonelo, ikheli lomsebenzisi lomsebenzisi). Le nkampani ilandela imigomo emihle kuphela: ukwandisa ijubane lomsebenzi futhi uthole ulwazi oludingekayo ukuze uthuthukise labo. isevisi.
Masithemba ukuthi yindlela okuyiyo

Indlela yokubhalisa i-DNS 8.8.8.8, 8.8.4.4 - imiyalelo ngesinyathelo ngesinyathelo
Manje sizocabangela ukuthi singabhalisa kanjani i-DNS edingekayo kwikhompyutha eqhuba i-Windows 7, 8, 10 (ku-XP ngokufanayo, kodwa ngeke ngihlinzeke ngama-skrini ...).
ISINYATHELO 1
Vula iphaneli yokulawula i-Windows ku: Inethiwekhi Yokulawula Inethiwekhi ne-Inthanethi Inethiwekhi Nesikhungo Sokwabelana
Ngaphandle kwalokho, ungakwazi ukumane uchofoze isithonjana senethiwekhi nge inkinobho yesokudla yegundane bese ukhetha isixhumanisi "Soxhumanoningi Nokwabelana" (bheka Umfanekiso 1).
Umdwebo. 1. Iya esikhungweni sokulawula inethiwekhi
ISINYATHELO 2
Ngakwesobunxele, vula isixhumanisi "Shintsha izilungiselelo ze-adapter" (bheka Umfanekiso 2).
Umdwebo. 2. Isikhungo Nokwabelana
ISINYATHELO 3
Okulandelayo, udinga ukukhetha uxhumano lwenethiwekhi (ofuna ukuguqula i-DNS, lapho ufinyelele khona ku-Inthanethi) futhi uye ezindaweni zayo (chofoza ngakwesokudla uxhumano, bese ukhetha "izindawo" kwimenyu).
Umdwebo. 3. Izakhiwo zokuxhumana
ISINYATHELO 4
Khona-ke udinga ukuya ezakhiweni ze-IP version 4 (TCP / IPv4) - bheka umkhiwane. 4
Umdwebo. 4. Izakhiwo ze-IP version 4
ISINYATHELO 5
Okulandelayo, shintsha isilayidi ku- "Thola amakheli we-DNS elandelayo" isikhundla bese ufaka:
- Iseva ye-DNS ethandwayo: 8.8.8.8
- Enye iseva ye-DNS: 8.8.4.4 (bheka Umfanekiso wesi-5).
Umdwebo. 5. DNS 8.8.8.8.8 no 8.8.4.4
Okulandelayo, londoloza izilungiselelo ngokuchofoza inkinobho ethi "Kulungile".
Ngakho-ke, manje ungasebenzisa ijubane eliphezulu nokuthembeka kwamaseva e-DNS avela ku-Google.
Yonke into engcono kakhulu 🙂
