Iyini i-EDNS futhi ithuthukisa kanjani i-DNS ukuze isheshe futhi ivikeleke kakhulu?

Funda mayelana ne-EDNS nezinzuzo zayo ekuthuthukiseni i-DNS ukwenza i-inthanethi isheshe futhi iphephe.

Ngokungangabazeki, ngaphandle kwamaseva e-DNS, besingeke sikwazi ukungena ku-inthanethi njengoba senza nsuku zonke, lobu buchwepheshe bebubalulekile iminyaka engaphezu kwengu-30, kodwa manje buyavuselelwa.
Yebo, sikhuluma ngokufinyelela isandiso edns okusha lokho'vuselelaUmqondo we DNS.

Uma sithayipha ikheli lewebhusayithi kubha ye-URL yesiphequluli, ivele ithumele isicelo kuseva DNS (I-DNS noma ngesiNgisi: Domain Name System(ye-opharetha ye-inthanethi ukuxazulula ikheli le-IP)Iphrothokholi Ye-inthanethi noma ngesiNgisi: I-Inthanethi Protocol), eyabelwe igama lesizinda noma Domain.

Okuqukethwe yi-athikili umbukiso

Iyini i-EDNS?

Uma usuthole ikheli le-IP (Iphrothokholi Ye-inthanethi noma ngesiNgisi: I-Inthanethi Protocol), esinye isicelo sithunyelwa ku-IP (Internet Protocol) ukuze nje kutholwe idatha edingekayo ukuze kusetshenziswe ikhasi lewebhu elifanele.

Nokho, ukuze ufunde kabanzi mayelana edns Sizokutshela ukuthi kuyini edns Futhi ukuthi izothuthukisa kanjani i-DNS, yenze i-inthanethi isheshe futhi ivikeleke kakhulu. Lapho ukuthuthukiswa okukhulu kwezobuchwepheshe kuzokwenzeka noma njengoba inguquko ethule على Thuthukisa ukuphequlula kwe-inthanethi Okwethu kwansuku zonke ngaphandle kokuqaphela.

I-Internet Engineering Task Force ivumileIETF) Isikhathi eside ekucacisweni kokufika RFC 6891 noma izindlela zokunweba ze-DNS (edns). Leli zinga liqale ukusebenza ngoFebhuwari 1, 2019. Akukhona lokho kuphela, kodwa futhi kukhona uchungechunge lwentuthuko ku-DNS ekhona noma i-DNS.

Kalula nje, i-EDNS iyi-Extension Mechanisms ye-DNS (EDNS) iwumgomo wokucacisa usayizi wamapharamitha amaningi wephrothokholi ye-Domain Name System (DNS) ebenomkhawulo wosayizi othathwa njengonomkhawulo kakhulu umphakathi wobunjiniyela be-inthanethi ukuze ukhuphule ukusebenza kwephrothokholi.

I-EDNS iyithuthukisa kanjani i-DNS ukwenza i-inthanethi isheshe futhi ivikeleke kakhulu?

Isistimu ye-DNS inesibopho sokushintsha amakheli noma ama-URL esiwafaka esipheqululini ekhelini le-IP elihambisanayo ukuze sisungule uxhumano. Kuze kube ngu-1983, kwasetshenziswa uhlelo UMPHATHI , ifayela eligcina zonke izizinda ze-inthanethi ezaziwayo, kodwa lokhu sekungenzeki ngenxa yokukhula okukhulu kwe-inthanethi.

Namuhla, amasistimu esandiso we DNS ukuze amandla, indalo engenza amaseva e-DNS asheshe futhi asebenze kahle kakhulu kunangaphambili. Lokhu akukwazi nje ukwenza izinguquko kalula noma ngokushesha kuthuthukise ukutolika kwazo, kodwa izindlela zokuphepha zingahlanganiswa ukuze kuvikelwe ekuhlaselweni. DDoS.

Akulona uhlelo lokuqala lwesandiso lwe-DNS (edns) yanyatheliswa, njengoba uhlelo lokuqala lwanyatheliswa ngo-1999 yi-Internet Engineering Task Force njenge RFC 2671. Kodwa-ke, lokhu sekuvele kumenyezelwe ukuthi akusasebenzi ngokucaciswa RFC 6891 okusha. Ngenhlanhla, njengabasebenzisi, akudingeki ukhathazeke nganoma yini ngoba zonke izinguquko kanye nentuthuko incike ezinkampanini ezibhekene nazo. DNS.

Kodwa-ke, sizoqhubeka nokuzulazula ngokujwayelekile futhi sisebenzise ukuthuthukiswa, okungase kufihlwe ngezinye izikhathi. Ngokuhlanganiswa nezinkampani, kuzodingeka bahlole ukuthi uhlelo lwabo luyahambisana yini nalo, futhi uma kungenjalo, kuzodingeka babuyekezele kumazinga amasha.

Lokhu kwakungolunye ulwazi olutholakalayo okwamanje mayelana ne-EDNS nokuthi ithuthukisa kanjani i-DNS ukuze isheshe futhi ivikeleke kakhulu.

Sithemba ukuthi uzothola le ndatshana ilusizo ukuthi uyazi Iyini i-EDNS futhi ithuthukisa kanjani i-DNS ukuze isheshe futhi ivikeleke kakhulu. Yabelana ngombono wakho nesipiliyoni nathi kumazwana abekiwe.
