Uma ikhasi lewebhu lithatha isikhathi eside ukulayisha, ungase umangale ukuthola ukuthi akulona uxhumano lwakho lwe-inthanethi oluyinkinga, kodwa izilungiselelo zakho ze-DNS. Nasi isizathu.
Kungenzeka ukuthi uzwile abantu bekutshela ukuthi ushintshe i-DNS yakho uma isivinini sakho se-inthanethi sihlupheka. Abanye bangase bathi ukushintsha izilungiselelo zakho ze-DNS kungaphinda kabili isivinini sakho se-inthanethi!
Izilungiselelo zakho ze-DNS zidlala indima ebaluleke kakhulu kuzivinini zakho zokuphequlula. Usebenzisa i-DNS njalo, noma ungayazi. Ngakho-ke ake sixoxe ngokuthi iyini i-DNS nokuthi kungani izilungiselelo ze-DNS zithinta isivinini sakho se-inthanethi.
Iyini iseva ye-DNS?
I-DNS isifinyezo esilula seSistimu Yegama Lesizinda. Kucabange njengohlu lwemibhalo olukhulu oluqopha wonke amakheli aku-inthanethi. Uma uthayipha i-URL esipheqululini sakho, ihunyushwa ekhelini le-IP yisiphequluli sakho sisebenzisa amarekhodi e-DNS.
Yonke idivayisi exhunywe ku-inthanethi inekheli layo le-IP. Ngaphandle kwamaseva e-DNS, kufanele ulondoloze ikheli le-IP ngalinye ukuze ufinyelele iwebhusayithi ethile. Kodwa, ngenhlanhla, ngamarekhodi e-DNS, igama lokusingatha lihunyushwa ngokuzenzakalelayo ekhelini le-IP, futhi isiphequluli sakho sithumela isicelo kuseva, esibuyisela izinsiza ezilayisha isayithi lakho.
Kukhona amaseva I-DNS enamandla Futhi amaseva e-DNS amile. Eyangaphambili ibuyekeza amarekhodi e-DNS njalo njengoba amakheli e-IP ashintsha. kuningi Abahlinzeki be-DNS yamahhala ongayisebenzisa futhi.
Iseva ye-DNS iyithinta kanjani isivinini
Ukuze uqonde ukuthi iseva ye-DNS ithinta kanjani isivinini, kubalulekile ukugxila kumarekhodi e-DNS, okubaluleke kakhulu okuyirekhodi elithi A, elimele "ikheli".
Irekhodi A libonisa wonke amagama wesizinda kumakheli e-IP. Uma ufinyelela iwebhusayithi, i-DNS ixazulula umbuzo wakho, ihumushe i-URL ekhelini le-IP, bese ikhomba iseva lapho iwebhusayithi isingathwe khona.
Uma isikhathi sokuphendula siphezulu kuseva ye-DNS, singanciphisa inqubo yokuxazulula igama lewebhusayithi. Lokhu kungase kubangele ukuthi iwebhusayithi ilayishe kancane kunalokho obukulindele.
Ngokuzenzakalelayo, iseva ye-DNS ikhethwa ngokuzenzakalelayo, nakuba amanye ama-ISP angase asebenzise iseva ye-DNS ethile eseduze nomsebenzisi ngokwendawo.
Kodwa, uma amaseva e-DNS engaphansi komthwalo osindayo wethrafikhi, kuzobangela isivinini sokulungiswa kwegama, okuzonciphisa ukusebenza kokuphequlula. Ngokufanayo, uma iseva ye-DNS itholakala kude kakhulu nalapho uhlala khona, kuzothatha isikhathi eside ukuxazulula imibuzo yewebhusayithi.
ungakwazi Shintsha izilungiselelo zakho ze-DNS ukuze uthuthukise isivinini sakho se-inthanethi Nokho, akusona isixazululo esilingana konke. Ngokufanelekile, uzofuna ukukhetha iseva ye-DNS eseduze nawe futhi enamarekhodi akamuva.
Amawebhusayithi aku-inthanethi asabalale kuzo zonke iziphakeli noma amanodi. Abantu abaningi basebenzisa inethiwekhi yokulethwa kokuqukethwe (CDN). Cloudflare noma Google DNS Ukuthuthukisa ukusebenza nokulayisha amasayithi abo ngokushesha.
Amafayela angumongo asakazwa kunethiwekhi yonkana, kunokuba agcinwe kuseva efanayo. Lokhu kunciphisa isikhathi sokuphendula futhi kuthuthukisa isikhathi esisithathayo ukuze iwebhusayithi yakho ilayishe.
Isibonelo, ake sithi utholakala e-Canada futhi ulanda ifayela ngewebhusayithi esebenzisa i-Cloudflare. Uma amarekhodi akho amadala e-DNS A exazulula umbuzo kuseva yase-Canada, izivinini zakho zizoba zinhle kakhulu.
Nokho, uma i-DNS ixazulula umbuzo wakho kuseva yase-UK, isibonelo, uzobona isivinini sokuxhuma esinensa. Khumbula ukuthi imibuzo ye-DNS ngokuvamile ayithinti isivinini sokulanda, kodwa ibangela amawebhusayithi ukuthi alayishe kancane.
Ungayithola kanjani iseva engcono kakhulu ye-DNS
Sebenzisa i-Namebench Enye yezindlela ezinhle kakhulu zokuthola iseva ye-DNS eshesha kakhulu. Lolu uhlelo olulula oludizayinwe i-Google olukuvumela ukuthi ukhombe ngokushesha amaseva e-DNS ahloliwe eduze nendawo yakho. Nansi indlela esebenza ngayo:
1. Landa futhi ufake i-Namebench
Uma usulande futhi ufake i-Namebench, kuzodingeka ungeze iseva ye-DNS oyisebenzisayo. Ezimweni eziningi, i-Namebench izothola ngokuzenzakalelayo futhi igcwalise iziphakeli zamagama ozisebenzisayo, njengoba kuchazwe ngenhla.
Leli yifayela eliphathekayo elisebenzisekayo, ngakho-ke asikho isidingo sokufaka noma yini. Vele ulande futhi ukhiphe uhlelo lokusebenza futhi luzosebenza ngaso leso sikhathi.
2. Qalisa ibhentshimakhi
Uma usuqalise ibhentshimakhi, i-Namebench izokukhombisa imiphumela. Ukutolika le miphumela, ekhonjiswe ngezansi, kungaba yinto ekhohlisayo, kodwa ngokufanelekile, ufuna nje ukunaka izincomo eziphezulu. Nansi indlela ebukeka ngayo:
Uma ubheka phezulu, i-DNS eyinhloko yamanje ishesha kakhulu, okusho ukuthi asikho isizathu sokushintsha izinto. Ungakwazi futhi ukubona ukucushwa okunconyiwe kwesokudla, okuhlanganisa amaseva ayinhloko, esibili, nawemfundo ephakeme.
Bese, i-Namebench ikukhombisa wonke amaseva e-DNS ahloliwe, kanye nemiphumela ngayinye. Ungabona ngisho nesikhathi sokuphendula esimaphakathi neminye imininingwane yobuchwepheshe uma uskrolela phansi.
3. Shintsha amaseva e-DNS (uma kunesidingo)
Khumbula ukuthi kuzodingeka ushintshe iseva ye-DNS yawo wonke amadivayisi axhunyiwe. Ngakho-ke, isibonelo, uma uxhumeke ku-inthanethi usebenzisa enye idivayisi, njenge-PlayStation 5, ungase ufune ukushintsha i-DNS nalapho.
Kungani amaseva e-DNS ethinta isivinini sakho se-inthanethi
Ngokungangabazeki into ebaluleke kakhulu izikhathi zakho zokubheka i-DNS, okuyilapho i-DNS yakho ixazulula umbuzo wakho. Uma ihamba kancane, kuzothatha isikhathi eside ukuthi iwebhusayithi yakho ilayishe. Ngokufanayo, uma inqolobane ye-DNS isanda kususwa, kungase kuthathe isikhathi ukuze amarekhodi amasha agcinwe.
I-DNS izohlola inqolobane yesiphequluli sakho, inqolobane yesistimu yokusebenza, futhi ithumele nesicelo kuseva ye-DNS ephindayo (ehlinzekwe yi-ISP yakho) ukuze ixazulule umbuzo.
Isiphetho: Ingabe Kufanele Ushintshe Izilungiselelo Zakho Ze-DNS?
Kubalulekile ukuqaphela ukuthi ukushintsha izilungiselelo zakho ze-DNS ngeke kudingeke ngaso sonke isikhathi, njengoba i-ISP yakho ngokuvamile izokuxhuma kuseva ye-DNS esebenza ngokushesha.
Kodwa uma usohambweni noma uxhuma kuseva ye-DNS engabuyekeziwe noma engekho, ungase ube nesivinini esinensayo. Ukushintsha izilungiselelo zakho ze-DNS kuzosiza nakanjani. Kwezinye izimo, ukusebenzisa i-Smart DNS nakho kungasiza.
