I-VPN vs i-Private DNS: Umhlahlandlela Ophelele Wokuqonda Umehluko Wabo Nokusetshenziswa Kwabo

I-Universal Adventure » Okuvamile » I-VPN vs I-DNS Eyimfihlo: Umhlahlandlela Ophelele Wokuqonda Umehluko Nokusetshenziswa Kwawo

Cishe uke wahlangana namagama athi VPN kanye ne-DNS yangasese ngenkathi ufuna izindlela zokwenza ukuphequlula kwakho kuphephe kakhudlwana. Uma uqala ukubuka, kungase kubonakale sengathi kwenza into efanayo ngoba zombili zithembisa ubumfihlo obengeziwe, kodwa iqiniso liwukuthi zihluke ngokuphelele. Ngenkathi eyodwa iqinisekisa ukuthi akekho owaziyo ukuthi ungqongqoza kuyiphi "iminyango", enye yakha umhubhe ophephile ukuze kungabikho muntu obona okungaphakathi kwesikhwama sakho.

Ukuphequlula i-inthanethi namuhla ngaphandle kokucabanga ngokuphepha, empeleni, kuwukudlala ngomlilo. Phakathi kwabahlinzeki be-inthanethi abahlola yonke into kanye nohulumeni abamisa izithiyo noma kuphi lapho bethanda khona, ukuqonda la mathuluzi kubalulekile ekususeni umkhondo wakho ku-inthanethi nokuzivikela. Kulesi sihloko, sizochaza indlela asebenza ngayo , ukufana kwawo, futhi, ngaphezu kwakho konke, ukuthi kungcono nini ukusebenzisa elilodwa noma elinye ukuze ungakhwabani.

Iyini i-DNS futhi kungani ibalulekile?

Ukuze uqonde i-DNS yangasese, okokuqala udinga ukwazi ukuthi iyini i-DNS evamile. Cabanga ukuthi uhlu loxhumana nabo lwe-inthanethi . Amakhompyutha awaqondi amagama anjenge-"google.com"; kunalokho, axhumana esebenzisa izinombolo ezibizwa ngamakheli e-IP. I-DNS inesibopho sokuhumusha lelo gama elisebenziseka kalula libe ikheli le-IP elingaqondwa umshini.

Nansi inkinga: ngokuzenzakalelayo, umhlinzeki wakho wesevisi ye-inthanethi (i-ISP) uphatha lokhu kuhumusha. Lokhu kusho ukuthi umhlinzeki wakho wazi kahle ukuthi yimaphi amakhasi owavakashelayo, noma ngabe akakwazi ukubona okuqukethwe okuqondile kwalokho okwenzayo kuwo uma iwebhusayithi isebenzisa i-HTTPS. Ngaphezu kwalokho, ama-ISP amaningi asebenzisa i-DNS ukuvimbela noma ukuvimbela amawebhusayithi, ngokumane abike ukuthi "umhumushi" akakho.

Ukuya ku-Private DNS: Vala imibuzo yakho

I-DNS yangasese ayishintshi umsebenzi wokuhumusha oyisisekelo, kodwa ingeza ungqimba lokubethela kwesimanje . Esikhundleni sokuthumela umbuzo ngombhalo ocacile (ongafundwa yinoma ubani endleleni), isebenzisa amaphrothokholi afana ne -DoH (DNS-over-HTTPS) noma i-DoT (DNS-over-TLS) ukuze isicelo sihambe sibethelwe.

Kunezindlela eziningana zokufeza lokhu. I-DoH ixuba ithrafikhi ye-DNS nethrafikhi evamile yewebhu (i-port 443), okwenza kube nzima ukuthi abaqaphi benethiwekhi bayibone. Ngakolunye uhlangothi, i-DoT isebenzisa i-port 853 , eqondile kakhulu kodwa kulula ukuthi abaphathi benethiwekhi bayivimbe. Kukhona ne-DNSCrypt, umakadebona weqembu futhi enamandla kakhulu, yize ingahambisani nawo wonke amadivayisi.

Amandla ama-VPN: Ukuvikelwa okuphelele

I-VPN, noma i-Virtual Private Network, idlulela phambili kakhulu. Ayihumushi amagama kuphela; idala umhubhe ofihliwe, osuka komunye uye komunye phakathi kwedivayisi yakho neseva ekude. Uma uxhuma, yonke ithrafikhi yakho ye-inthanethi, ngaphandle kokukhetha, ihamba kulo mhubhe. Lokhu kusho ukuthi ikheli lakho langempela le-IP lifihliwe futhi lithathelwe indawo ikheli le-IP leseva ye-VPN.

Ngenxa yalokhu, ungenza izinto iseva ye-DNS engazivumeli, njengokudlula imikhawulo yendawo . Uma ufuna ukufinyelela ikhathalogi yesiJapane ye-Netflix, umane uxhumeke kuseva lapho, futhi iwebhusayithi izocabanga ukuthi usendaweni yaseJapane. Ngaphezu kwalokho, i-VPN ivikela idatha yakho kumanethiwekhi omphakathi we-Wi-Fi, ivimbela noma yimuphi umgebengu ukuthi abambe ulwazi lwakho.

Ukuqhathanisa okuqondile: Yimiphi umehluko wangempela?

Ukuze sigweme ukudideka, ake sihlaziye amaphuzu lapho lobu buchwepheshe obubili bungqubuzana khona. Ngokuphathelene nokuphepha nobumfihlo , ama-VPN ayanqoba ngoba abhala ngemfihlo yonke idatha, kuyilapho i-DNS yangasese ibhala ngemfihlo kuphela umbuzo mayelana nendawo yewebhusayithi.

• Ijubane: Lapha, i-DNS yangasese inenzuzo. Njengoba kungadingeki ukuthi ibethele yonke ithrafikhi noma idlule kuseva yomlamuleli ekude, umthelela esivinini awukhoI-VPN, kuye ngekhwalithi yayo, inganciphisa kancane ijubane lokuxhumana.
• Ukuhambisana: Ukusetha i-DNS kulula kakhulu futhi kuhambisana cishe nanoma yini, kusukela kuselula kuya ku-game console. I-VPN ivame ukudinga i- uhlelo lokusebenza lwendabuko noma ukucushwa kwe-router okuyinkimbinkimbi kakhulu.
• Izindleko: Izinsizakalo eziningi ze-DNS ezizimele zimahhala noma zishibhile kakhulu. Ama-VPN asezingeni eliphezulu ahlonipha ngempela ubumfihlo ngokuvamile adinga i- ukubhaliswa kwanyanga zonke.

I-SmartDNS: Iphuzu eliphakathi nendawo

Kukhona ne-SmartDNS, okuyi-DNS exubile eneseva ye-proxy. Inhloso yayo akuyona ubumfihlo, kodwa ukukhohlisa izinsizakalo zokusakaza ukuze zinikeze ukufinyelela kokuqukethwe okuvela kwamanye amazwe ngaphandle kokunciphisa isivinini. Inkinga ukuthi ayinikezi ukubethela noma ukufihla ikheli lakho langempela le-IP, okwenza kube ithuluzi elilula, hhayi ikhambi lokuphepha.

Zingasetshenziswa ndawonye noma kuwukuchitha imali?

Nasi umehluko obalulekile. Cishe wonke ama-VPN e-premium asevele equkethe amaseva awo e-DNS ayimfihlo . Uma usebenzisa i-VPN, imibuzo yakho ye-DNS isivele ihamba ngomhubhe obethelwe. Ukuzama ukusetha i-DNS yangasese yangaphandle ngenkathi usebenzisa i-VPN kungaba yinto engasizi ngalutho, njengoba kungaholela ekuvuzeni kwe-DNS , okubangela ukuthi ezinye izicelo ziphume emhubheni futhi zembule umsebenzi wakho.

Indlela yokuvimbela ifoni yakho ephathekayo ukuthi ikulalele futhi ivikele ubumfihlo bakho

Uma ungayisebenzisi i-VPN, ukusetha i-DNS yangasese (njengaleyo evela ku-Cloudflare noma i-Quad9) kuwumqondo omuhle kakhulu wokuvimbela umhlinzeki wakho we-inthanethi ukuthi agcine irekhodi eliningiliziwe lomsebenzi wakho. Kodwa uma usuvele une-VPN enhle esebenzayo, asikho isidingo sokwenza izinto zibe nzima ngokuhlela amaseva e-DNS engeziwe.

Ukusetha okusheshayo kumadivayisi akho

Uma usukhethe i-DNS yangasese, ukuyisetha kuyinto elula. Ku -Android , mane nje uye ku-Network & Internet bese ubheka inketho ethi "Private DNS" ukuze ufake igama le-hostname. Ku -Windows noma ku-Mac , ukwenza lokhu kusuka kuzakhiwo zenethiwekhi, ushintsha amakheli e-IP e-DNS abe yinto efana ne-1.1.1.1 noma i-8.8.8.8.

Nge-VPN, indlela elula ukulanda uhlelo lokusebenza olusemthethweni lomhlinzeki, ukhethe izwe lakini, bese uchofoza inkinobho yokuxhuma.

Ukuvela kobuchwepheshe: Kusukela ku-IPv4 kuya ku-IPv6 kanye nokubethela kwe-TLS

Konke lokhu kwenzeka endaweni eshintsha njalo. Sisuke ku-IPv4 (enamakheli ayo alinganiselwe angu-32-bit) saya ku -IPv6 , enikeza inani elikhulu lamakheli ukuze kungabikho divayisi eshiywa ingenalo uxhumano. Lokhu kulethe izinhlobo ezintsha zamarekhodi e-DNS, njengerekhodi le -AAAA , ezidingekayo ukuphatha lawa makheli amade.

Ngesikhathi esifanayo, ukuphepha sekuthuthukile. I-SSL endala inikeze indawo i -TLS (Transport Layer Security) , okuyiphrothokholi manje esekela ukubethela okuningi kuwebhu futhi iyisisekelo lapho izinhlelo ze-DNS zangasese zanamuhla zisebenza khona ukuqinisekisa ukuthi ulwazi alushintshi.
