DNS Cache Poi\u00adso\u00adning (Ver\u00adgif\u00adten des DNS-Zwi\u00adschen\u00adspei\u00adchers) ist eine Tech\u00adnik, mit der DNS-Ser\u00advern schein\u00adbar g\u00fcl\u00adti\u00adge Ant\u00adwor\u00adten auf von ihnen gestell\u00adte Anfra\u00adgen simu\u00adliert wer\u00adden, hin\u00adter denen jedoch betr\u00fc\u00adge\u00adri\u00adsche Absich\u00adten ste\u00adcken.<\/p>\n\n\n\n
