Sawubona ntambama
Abasebenzisi abaningi, ikakhulukazi labo abebesebenzisa ikhompyutha izinsuku eziningana, okungenani bake bezwa ngesithonjana se-DNS (kulokhu, lesi akusona isitolo sezinto zekhompyutha).
Ngakho-ke, uma unezinkinga nge-Intanethi (ngokwesibonelo, amakhasi e-Inthanethi avulekile isikhathi eside), labo basebenzisi abanolwazi oluningi bathi: "le nkinga ingahle ihlobene kakhulu ne-DNS, zama ukuyiguqula ibe yi-DNS kusuka kuGoogle 8.8.8.8 ..." . Imvamisa, ngemuva kwalokhu kuza ukungaqondi okuningi ...
Kulesi sihloko ngifuna ukuxoxa kabanzi ngalolu daba, futhi sihlaziye nezinkinga eziyisisekelo ezihlobene nalesi sigatshana. Futhi ...
I-DNS 8.8.8.8 - kuyini futhi kungani kudingeka?
Ukunaka, ngokuhamba kwesikhathi esihlokweni amanye amagama aguqulwa ukuze aqondwe kalula ...
Zonke izingosi ozivula kwisiphequluli zigcinwa ngokomzimba ekhompyutheni (ebizwa ngokuthi iseva) enekheli lazo le-IP. Kodwa lapho sifinyelela isiza, sifaka hhayi ikheli le-IP, kepha igama lesizinda eliqondile (isibonelo, //pcpro100.info/). Ngakho-ke ikhompyutha ilithola kanjani ikheli le-IP elifunekayo leseva lapho isayithi esivula kulo litholakala khona?
Kulula: sibonga i-DNS, isiphequluli sithola imininingwane ngokuxhumana kwegama lesizinda ngekheli le-IP. Ngakho-ke, okuningi kuncike kwiseva ye-DNS, ngokwesibonelo, ijubane lokulayisha amakhasi e-web. Uma iseva ye-DNS ithembeke futhi ishesha, umsebenzi wakho wekhompyutha ubushesha futhi ukhululekile.
Kepha kuthiwani ngomhlinzeki we-DNS?
Abahlinzeki be-DNS ongena kuyo i-Intanethi abasheshisi futhi abathembekile njengama-DNS avela kwaGoogle (ngisho nabanikezeli abakhulu be-Intanethi bayona ngokuwa kwamaseva abo e-DNS, ingasaphathwa eyincane). Ngaphezu kwalokho, ijubane lamaningi lishiya okufiselekayo.
I-Google Public DNS inikezela amakheli alandelayo omphakathi ngemibuzo ye-DNS:
- 8.8.8.8
- 8.8.4.4
-
IGoogle ixwayisa ukuthi i-DNS yayo izosetshenziswa kuphela ukusheshisa ukulayisha amakhasi. Amakheli we-IP wabasebenzisi azogcinwa database kuphela amahora angama-48, inkampani ngeke igcine imininingwane yomuntu (ngokwesibonelo, ikheli lendawo yomsebenzisi) noma ikuphi. Inkampani iphishekela kuphela izinhloso ezinhle kakhulu: ukukhulisa ijubane lomsebenzi nokuthola ulwazi oludingekayo lokuthuthukisa lezo. inkonzo.
Asithembe ukuthi indlela injalo 🙂

Ungayibhalisa kanjani i-DNS 8.8.8.8, 8.8.4.4 - imiyalelo ngesinyathelo
Manje, ake sibheke ukuthi singabhalisa kanjani ama-DNS adingekayo kukhompyutha esebenzisa iWindows 7, 8, 10 (kwi-XP kuyafana, kepha angizukuhlinzeka ngemifanekiso-skrini ...).
ISINYATHELO 1
Vula iphaneli yokulawula yeWindows ku: Iphaneli Yokulawula Inethiwekhi ne-Inthanethi Inethiwekhi kanye neSikhungo Sokwabelana
Noma ungavele uchofoze isithonjana senethiwekhi ngenkinobho yegundane elifanele bese ukhetha ilinki ethi "Inethiwekhi Nokwabelana Isikhungo" (bheka umdwebo 1).
U-fig. 1. Iya esikhungweni sokulawula inethiwekhi
ISINYATHELO 2
Kwesobunxele, vula isixhumanisi esithi "Shintsha izilungiselelo ze-adaptha" (bheka. Fig. 2).
U-fig. 2. Isikhungo Senethiwekhi Nokwabelana
ISINYATHELO 3
Okulandelayo, udinga ukukhetha ukuxhumana kwenethiwekhi (ofuna ukuguqula i-DNS ngalo ongena kulo kwi-Intanethi) bese uya kuzakhiwo zayo (chofoza ngakwesokudla ekuxhumekeni, bese ukhetha "izakhiwo" kumenyu).
U-fig. 3. Izindawo Zokuxhuma
ISINYATHELO 4
Ngemuva kwalokho udinga ukuya ezimeni zenguqulo ye-IP 4 (TCP / IPv4) - bheka umkhiwane. 4.
U-fig. 4. Izakhiwo zohlobo lwe-IP 4
ISINYATHELO 5
Okulandelayo, shintshela isilayida endaweni ethi "Thola amakheli e-DNS alandelayo" bese ufaka:
- Okuncanyelwayo Isiphakeli se-DNS: 8.8.8.8
- Enye iseva ye-DNS: 8.8.4.4 (bheka umfanekiso 5).
U-fig. 5. I-DNS 8.8.8.8.8 ne-8.8.4.4
Okulandelayo, gcina izilungiselelo ngokuchofoza inkinobho "Kulungile".
Ngakho-ke, manje ungajabulela ijubane eliphakeme nokwethembeka kwamaseva we-Google DNS.
Konke okuhle 🙂
