Yintoni i-DNS server?
apho igama (Inkqubo yamagama eDomainkwizinto ezimbini, eyokuqala yinkqubo esetyenzisiweyo namhlanje kwiimeko ezininzi ukuguqula iilebheli ezinokufundeka (Njengamagama abamba iikhompyuter) kwiidilesi zedijithali, okwesibini ngumsebenzi wehlabathi wokwakha inkonzo usebenzisa le protocol ukwenza ukuba unxibelelwano.
kwaye i DNS sisishunqulelo se umncedisi wegama lesizinda okanye Inkqubo yegama lesizinda
Inkqubo yeDomain Name (DNSiseti yolwazi oluguqulela amagama asingathi kwiidilesi ze-IP.
I-DNS ihlala ibizwa ngokuba yincwadi yefowuni ye-Intanethi kuba iguqula amagama akhunjulwayo alula njenge-www.google.com kwiidilesi ze-IP ezinje nge-216.58.217.46.
Kwenzeka emva kwezigcawu emva kokuchwetheza i-URL kwindawo yedilesi yesikhangeli ngaphandle kokuba umsebenzisi ayiphawule le nkqubo.Kufanelekile ukuba uqaphele ukuba ngaphandle kweseva ye-DNS, ukuhamba kwi-Intanethi akuyi kuba lula kuba kuya kufuneka singene kwidilesi ye-IP yewebhusayithi nganye sifuna ukutyelela.
Amanqanaba okuQalwa kwe-DNS
Le nkonzo idlulile kwizizukulwana ezithathu yade yaya kuba ikwimo yesiqhelo kunye nesiko.
● Isizukulwana sokuqala
Emva kwemizamo yokuqala yokwenza ukuba iinginginya zifikeleleke kwi-Intanethi, iqela leenjineli lenze inkcazo ye-DNS.
Lo msebenzi wenziwa ngaphakathi kwe-Intanethi yoQeqesho lobuNjineli be-Intanethi (IETF) kunye namaxwebhu athunyelwe kuLuhlu lweSicelo seNgxelo (RFC), Olu xwebhu luchaza umthetho olandelwayo osebenza ngokupheleleyo kwaye lubandakanya ezinye zeentlobo zedatha zakuqala eziza kudluliselwa.
Imeyile ye-Intanethi ikwachongiwe kwaye bekukho iinzame zokuvumela iposi ukuba isebenzise ngokubonakalayo DNS. Nangona ezinye iinzame zilandelwe ukongeza usetyenziso oluthile kwi-DNS, khange ilandelwe kuba kamva kuye kwavela ukuba yayingengombono wokudibanisa ezinye ii -apps ngokunzulu kwi-DNS. DNS Umbono olungileyo kwaye yayimalunga neminyaka eli-10 ngaphambi kokuba kupapashwe uhlaziyo lwenkqubo yokuqala DNS Yeyiphi yokongeza indlela enamandla ngakumbi yokugcina iiseva zihlaziyiwe kusetyenziswa iindlela ezibiziweyo QAPHELA kunye nokudluliselwa kwendawo eyonyukayo (IXFR), kwisizukulwana sokuqala se DNS, eyona ndlela yokubonelela ngokuqhubeka yayikukuba neeseva ezininzi eziphendula imibuzo emininzi. Omnye umncedisi wabizwa ngokuba ngumncedisi omkhulu (inkosi yomncedisi), Ngelixa abanye babengamaseva amakhoboka (amakhoboka), kwaye iserver nganye yamakhoboka yayalelwa ukuba itshekishe iserver master ngamaxesha athile ukumisela ukuba idatha itshintshile okanye hayi.
● Isizukulwana sesibini
inde QAPHELA Umtshintshi wokuqala womdlalo, endaweni yokuba umncedisi oyintloko alinde iiseva zekhoboka ukuba zihlolisise, angathumela umyalezo wesaziso kwiiseva zekhoboka, ezibangela ukuba bafumane idatha entsha. Kwangelo xesha kwenziwa IXFR utshintsho olukhulu kwindlela yokwaziswa kwedatha;
Ngaphambili, ukutshintsha irekhodi elinye kuphela kumakhulu kwenza ukuba imigaqo-nkqubo yoqobo ithumele amakhulu emiyalezo, ngelixa utshintsha IXFR Inkqubo ivumela kuphela utshintsho oluthunyelwe.
● Isizukulwana sesithathu
Kwaye emva kokongeza QAPHELA و IXFR kunye nohlaziyo olubalulekileyo, ukwenziwa komgaqo olandelwayo sele kuqalile DNS Kwingxakeko, njengoko ikhowudi yongezwa apha naphaya, kodwa akukho namnye owanike iiprotocol ukujonga kakuhle into ebizwa ngokuba yimfezeko yolwakhiwo, ugxininiso lophuhliso kwisizukulwana sesithathu yayilukhuseleko DNS Kwaye iya kuhlala injalo iminyaka emininzi ezayo.
Isebenza njani iseva ye-DNS
Inkqubo inokuba nobunzima kodwa inokwenziwa lula ngokuthi iseva DNS
Yimephu apho i-Intanethi isebenza khona ngendlela oyaziyo; Ngelixa, xa ufaka igama lewebhusayithi kwisikhangeli sakho, iserver DNS ukukusa kwidilesi IP ichanekile. Kuthatha amanqanaba aliqela kunye neeseva ezininzi, kodwa inkqubo iyakhawuleza kakhulu.
Ukuqonda inkqubo esombulula isisombululo se-DNS, kubalulekile ukuba wazi izinto ezahlukeneyo zekhompyuter ekufuneka umbuzo we-DNS ugqithe. Kwibhrawuza yewebhu ukukhangelwa kwe-DNS kwenzeka kwaye akufuneki nakuphi na ukusebenzisana kwikhompyuter yomsebenzisi ngaphandle kwesicelo sokuqala.
Zithini izinto zeDNS?
Kwi-DNS, inani lezinto ziyasebenzisana ukugqiba isicelo sakho:
● I-DNS kwakhona
Inokucingwa njengomgcini wethala leencwadi emcela ukuba akhangele incwadi ethile naphi na kwithala leencwadi, eyiyo DNS phinda kwakhona Uxanduva lokungenisa izicelo ezongezelelweyo, eziphucula ukukhangela kunye nokwanelisa umsebenzisi.
● Ingcambu nameserver
Linyathelo lokuqala lokuguqulela okanye lokusombulula amagama ehostele afundwayo kwiidilesi ze-IP.
Inokucingwa njengesikhombisi kwilayibrari esalatha kwiishelufa ezahlukeneyo zeencwadi; Ungayithatha njengesalathiso kwezinye iisayithi ezithile.
● Igama leseva yenqanaba eliphezulu
Umncedisi wenqanaba eliphezulu (TLDNjengeshelufu leencwadi elayibrari.
Eli gama lomncedisi linyathelo elilandelayo lokukhangela idilesi ethile ye-IP, njengoko ibamba indawo yokugqibela yegama lesiza.Umzekelo, masithi sinesiza esinegama example.com Idomain ekumgangatho ophezulu (com.).
● Igama eligunyazisiweyo
Yindawo yokugqibela kumbuzo weeseva, kwaye ukuba igama elisemthethweni liseva linokufikelela kwirekhodi eceliweyo,
Izakubuyisela idilesi ye-IP yegama lomamkeli eliceliweyo Umvavanyi we-DNS ngubani owenza isicelo sokuqala.
