Ukushintsha okulula kokumisa kungenza umehluko omkhulu (futhi ukhululekile)
Uyazi ukuthi ungakwazi ukuthuthukisa kokubili ukusebenza kwakho kokuphequlula i-intanethi nokuphepha ngokukhetha enye i-resolver DNS? Izindaba ezinhle ukuthi likhululekile futhi kuthatha cishe umzuzu wesikhathi sakho ukwenza ushintsho komunye umhlinzeki.
Kuyini i-DNS Resolver?
I- Domain Name System (i-DNS) ingase isuse kalula ulimi lomlawuli wakho wenethiwekhi eliseduzane, kepha umsebenzisi ojwayelekile akawazi noma anakekele ukuthi yi-DNS, noma yenzani kubo.

Uma unayo iseva futhi ufuna ukuvumela abantu ukuba bafinyelele kuso usebenzisa igama lesizinda, khona-ke ungakwazi ukukhokha imali bese ubhalisa igama lakho lesizinda eliyingqayizivele (uma litholakala) nge-Registrar ye-Intanethi njenge-GoDaddy.com, noma komunye umhlinzeki . Uma unegama lesizinda elixhunywe nekheli le-IP leseva yakho, khona-ke abantu bangaya esayithini lakho ngokusebenzisa igama lakho lesizinda esikhundleni sokuthayipha ikheli le-IP. Ama-server we-DNS "resolver" asiza ukwenza lokhu kwenzeke.
Iseva ye-DNS resolver ivumela ikhompyutha (noma umuntu) ukuthi ibheke igama lesizinda (ie) futhi ithole ikheli le-IP lekhompuyutha, iseva, noma enye idivaysi eyayiyo (okungukuthi 207.241.148.80). Cabanga nge-resolver ye-DNS njengencwadi yefoni yama-computer.
Uma uthayipha igama lesizinda sewebhusayithi kusiphequluli sakho sewebhu, ngemuva kwezingqimba, iseva ye-DNS yokuxazulula ikhompyutha yakho ekhomba yona isebenza ukucinga ezinye amaseva we-DNS ukucacisa ikheli le-IP elibizwa ngokuthi igama "lesizinda" ukuze isiphequluli sakho angaya futhi athole noma yini oyiphequlula leyo sayithi. I-DNS nayo isetshenziselwa ukusiza ukuthi uthole ukuthi iyiphi i-imeyli ye-imeyli umyalezo okufanele uhambe kuwo. Ineminye imigomo eminingi.
Iyini i-DNS Resolver yakho ehlelwe kuyo?
Abasebenzisi abaningi basekhaya basebenzisa noma yikuphi ukuxazulula i-DNS ukuthi abahlinzeki babo be-intanethi (ISP) bayabanika. Lokhu kuvame ukunikezwa ngokuzenzekelayo uma usetha imodemu yakho yekhebula / i-DSL, noma uma umzila wakho we-intanethi ongenazintambo / weshoni ngokuzenzakalelayo uphuma kwisiphakeli sakho se-ISP sika-DHCP bese uthatha ikheli le-IP lenethiwekhi yakho oyisebenzisayo.
Ungakwazi ukuthola ukuthi yini i-DNS resolver oyinikezwe ngokuya ekhasini "lokuxhuma" le-router yakho futhi ubheke ngaphansi kwesigaba "se-DNS Servers". Kuvame ukubili, okuyisisekelo nenye. Lawa maseva we-DNS angabanjwa yi-ISP yakho noma cha.
Ungabona futhi ukuthi iseva ye-DNS isetshenziswa yikhompyutheni yakho ngokuvula umyalezo wokubhala nokuthayipha i- " NSlookup " futhi ucindezela ukhiye wokungena. Kufanele ubone igama elithi "Default Server DNS" nekheli le-IP.
