CNAME ile alakal\u0131 bilmeniz gereken 5 kritik nokta;<\/span><\/p>\n

    \n
  1. CNAME (Canonical Name)<\/strong>, bir alan ad\u0131n\u0131 ba\u015fka bir alan ad\u0131na takma ad olarak ba\u011flayan DNS kay\u0131t t\u00fcr\u00fcd\u00fcr.<\/li>\n
  2. CNAME kay\u0131tlar\u0131, \u00f6zellikle www, blog ve shop gibi alt alan adlar\u0131n\u0131n y\u00f6netiminde ve \u00fc\u00e7\u00fcnc\u00fc taraf hizmet entegrasyonlar\u0131nda kullan\u0131l\u0131r.<\/li>\n
  3. CNAME ile A kayd\u0131 aras\u0131ndaki temel fark, CNAME’in ba\u015fka bir alan ad\u0131n\u0131, A kayd\u0131n\u0131n ise do\u011frudan IPv4 adresini<\/strong> hedeflemesidir.<\/li>\n
  4. CNAME sorgulama i\u015flemi, nslookup ve dig gibi ara\u00e7larla ger\u00e7ekle\u015ftirilerek bir alt alan ad\u0131n\u0131n hedefi kontrol edilebilir.<\/li>\n
  5. CNAME de\u011fi\u015fikliklerinin g\u00f6r\u00fcn\u00fcr hale gelme s\u00fcresi TTL de\u011ferine ve DNS \u00e7\u00f6z\u00fcmleyicilerinin \u00f6nbellek durumuna<\/strong> g\u00f6re farkl\u0131l\u0131k g\u00f6sterebilir.<\/li>\n<\/ol>\n<\/div>\n

    CNAME (Canonical Name), DNS (Domain Name System) \u00fczerinde bir alan ad\u0131n\u0131 ba\u015fka bir alan ad\u0131na takma ad olarak tan\u0131mlayan kay\u0131t t\u00fcr\u00fcd\u00fcr. CNAME kayd\u0131 sayesinde bir alt alan ad\u0131, do\u011frudan IP adresi belirtilmeden ba\u015fka bir alan ad\u0131n\u0131n DNS kay\u0131tlar\u0131 \u00fczerinden \u00e7\u00f6z\u00fcmlenebilir.<\/span><\/p>\n

    Bir \u00f6rnek olarak <\/span>www.turkishost.com<\/strong><\/span><\/a> adresi i\u00e7in <\/span>turkishost.com<\/span> hedefini g\u00f6steren bir CNAME kayd\u0131 olu\u015fturulabilir. B\u00f6ylece <\/span>www<\/span> alt alan ad\u0131, hedef alan ad\u0131n\u0131n adres kay\u0131tlar\u0131 \u00fczerinden \u00e7\u00f6z\u00fcmlenir. CNAME kay\u0131tlar\u0131 \u00f6zellikle alt alan ad\u0131 y\u00f6netiminde, bulut hizmetlerinde ve \u00fc\u00e7\u00fcnc\u00fc taraf platformlar\u0131n alan ad\u0131 do\u011frulama s\u00fcre\u00e7lerinde yayg\u0131n olarak kullan\u0131l\u0131r.<\/span><\/p>\n

B\u00f6ylece ayn\u0131 hizmete eri\u015fen farkl\u0131 alan adlar\u0131 i\u00e7in ayr\u0131 IP adresleri tan\u0131mlamak gerekmeyebilir.\u00d6zellikle birden fazla alt alan ad\u0131 kullanan web projelerinde CNAME kay\u0131tlar\u0131, altyap\u0131 de\u011fi\u015fikliklerinin y\u00f6netilmesini kolayla\u015ft\u0131rabilir. Yeni bir domain sorgulama<\/strong><\/a><\/span> ve sat\u0131n alma i\u015fleminde veya mevcut alan ad\u0131n\u0131n DNS kay\u0131tlar\u0131 d\u00fczenlendi\u011finde, uygun alt alan adlar\u0131 i\u00e7in CNAME tan\u0131mlamalar\u0131 yap\u0131labilir.
