Floating IP Ne Demek?<\/h2>\n

Floating IP<\/strong> belirli bir fiziksel sunucu<\/a> veya a\u011f aray\u00fcz\u00fcne kal\u0131c\u0131 olarak ba\u011fl\u0131 olmayan, dinamik olarak bir sunucudan di\u011ferine saniyeler i\u00e7inde aktar\u0131labilen genel yani public bir IP adresidir.<\/p>\n

Standart bir statik IP adresi tek bir makineye “\u00e7ivilenmi\u015f” haldeyken Floating IP bir sunucuda sorun ya\u015fand\u0131\u011f\u0131nda trafi\u011fi an\u0131nda yedek sunucuya y\u00f6nlendirmenize olanak tan\u0131r. Bu i\u015flem s\u0131ras\u0131nda DNS kay\u0131tlar\u0131n\u0131n g\u00fcncellenmesini beklemenize gerek kalmaz, \u00e7\u00fcnk\u00fc IP adresinin kendisi ayn\u0131 kal\u0131r sadece arka planda i\u015faret etti\u011fi hedef de\u011fi\u015fir.<\/p>\n
