DNS Nedir?<\/mark><\/h3>\n\n\n\n

DNS en genel anlam\u0131 ile kolay ve anla\u015f\u0131l\u0131r alan adlar\u0131na ula\u015fman\u0131z i\u00e7in kullan\u0131l\u0131r. D<\/strong>omain N<\/strong>ame S<\/strong>ystem i\u00e7in \u00e7al\u0131\u015fan \u00f6zel sunuculara DNS Sunucusu<\/strong> denir. Olduk\u00e7a basit bir kullan\u0131m alan\u0131na sahip olan bu sistemin as\u0131l amac\u0131, a\u011f \u00fczerinden gelen IP adresine ve alan ad\u0131na do\u011fru bir \u015fekilde yan\u0131t vermektir. \u0130nternet ortam\u0131nda bir \u015fey aramak istedi\u011finizde kar\u015f\u0131n\u0131za \u00e7\u0131kan yap\u0131 ve varaca\u011f\u0131n\u0131z yer DNS sistemi sayesinde belirlenir. DNS sunucular\u0131 asl\u0131nda 7\/24 \u00e7al\u0131\u015facak \u015fekilde konfig\u00fcre edilmi\u015f \u00f6zel bilgisayarlard\u0131r. T\u00fcm DNS sunucular\u0131 internet a\u011f\u0131nda uygun bir \u015fekilde DNS Zone\u2019lar\u0131na konumland\u0131r\u0131larak da\u011f\u0131t\u0131lm\u0131\u015ft\u0131r. Her biri kendi b\u00f6lgesinde s\u00fcrekli olarak IP adreslerini sorgulamak ve onlarla ili\u015fkili alan adlar\u0131n\u0131 e\u015fle\u015ftirmek ve onlar\u0131 kay\u0131t alt\u0131nda tutmak i\u00e7in \u00e7al\u0131\u015f\u0131rlar. <\/p>\n\n\n\n

DNS Sistemi Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/mark><\/h4>\n\n\n\n

\u0130nternette gezinmeyi kolay hale getiren DNS sistemi sunucu ve \u00e7\u00f6z\u00fcmleyicilerin bir araya gelmesi ile olu\u015fur. \u00c7\u00f6z\u00fcmleyici kavram\u0131 DNS istemcilerini ifade eder. DNS istemcilerinde sunucu ya da sunucular\u0131n adresleri yer al\u0131r. DNS istemci bir IP adresine ula\u015fmak istedi\u011finde isim sunucuya y\u00f6nelir. DNS veri taban\u0131nda sorulan isim yer al\u0131yorsa, DNS bu isme kar\u015f\u0131l\u0131k gelen IP adresini minimum s\u00fcrede sunucuya ula\u015ft\u0131r\u0131r.<\/p>\n\n\n\n

Burada yer alan bir veri taban\u0131na ula\u015fmak i\u00e7in t\u00fcm kay\u0131tlar\u0131n manuel \u015fekilde DNS sistemine girilmesi gerekir. \u0130nternet adresleri \u00fclkelere g\u00f6re farkl\u0131 isimlendirildi\u011fi i\u00e7in \u00f6ncelikle \u00fclke ayr\u0131m\u0131 yap\u0131l\u0131r. \u00dclke ayr\u0131m\u0131ndan sonra internet sitesinin alt b\u00f6l\u00fcmleri olan com, edu, gov gibi ayr\u0131mlara ge\u00e7ilir. T\u00fcrkiye\u2019ye ait olan t\u00fcm alt alan adreslerinin tr uzant\u0131s\u0131 ile bitti\u011fini g\u00f6rebilirsiniz. <\/p>\n\n\n\n

DNS sunucular\u0131, kendilerine ba\u011fl\u0131 olan Alan Adlar\u0131na atanan IP adreslerini kay\u0131t alt\u0131nda tutarak Root (K\u00f6k) DNS sunucular\u0131<\/strong> ile bu bilgiyi senkronize edecek \u015fekilde \u00e7al\u0131\u015f\u0131rlar. Sisteminde Alan Ad\u0131 bulunduran ve Hosting hizmeti veren t\u00fcm firmalar da kendilerine ait bir DNS sunucusuna sahiptir ve kendi sistemlerinde bar\u0131nd\u0131rd\u0131klar\u0131 alan adlar\u0131n\u0131 IP adresleri ile ili\u015fkilendirerek DNS sistemine kaydederler.<\/p>\n\n\n\n
