Uhlaziyo oluchanekileyo kumasebe azinzileyo we-BIND DNS iseva 9.11.18 kunye ne-9.16.2, kunye nesebe lokulinga 9.17.1, ekuphuhlisweni. Kukhupho olutsha ingxaki yokhuseleko ehambelana nokhuseleko olungasebenziyo kuhlaselo "Β» xa usebenza kwimowudi ye-DNS yezicelo zokuthumela iseva (ibhloko "yangaphambili" kwiisetingi). Ukongezelela, umsebenzi wenziwa ukunciphisa ubungakanani bezibalo zesignesha zedijithali ezigcinwe kwimemori ye-DNSSEC - inani lezitshixo ezilandelwayo liye lancitshiswa ukuya kwi-4 kwindawo nganye, eyaneleyo kwi-99% yamatyala.
Indlela "yokubuyisela i-DNS" ivumela, xa umsebenzisi evula iphepha elithile kwisiphequluli, ukuseka uqhagamshelo lweWebSocket kwinkonzo yenethiwekhi kwinethiwekhi yangaphakathi engafikelelekiyo ngokuthe ngqo kwi-Intanethi. Ukugqitha ukhuseleko olusetyenziswa kwizikhangeli ezichasene nokudlula umda wendawo yangoku (imvelaphi enqamlezayo), tshintsha igama lenginginya kwiDNS. Umncedisi we-DNS womhlaseli ulungele ukuthumela iidilesi ezimbini ze-IP enye enye: isicelo sokuqala sithumela i-IP yangempela yomncedisi kunye nephepha, kwaye izicelo ezilandelayo zibuyisela idilesi yangaphakathi yesixhobo (umzekelo, 192.168.10.1).
Ixesha lokuphila (TTL) lempendulo yokuqala libekwe kwixabiso elincinci, ngoko xa uvula iphepha, umkhangeli zincwadi unquma i-IP yangempela yomncedisi womhlaseli kwaye ulayishe imixholo yephepha. Iphepha liqhuba ikhowudi yeJavaScript elinda ukuba i-TTL iphelelwe lixesha kwaye ithumele isicelo sesibini, esichonga umphathi njenge-192.168.10.1. Oku kuvumela iJavaScript ukuba ifikelele kwinkonzo ngaphakathi kuthungelwano lwasekhaya, igqitha kuthintelo lwemvelaphi enqamlezayo. ngokuchasene nohlaselo olunjalo kwi-BIND isekelwe ekuthinteleni abancedisi bangaphandle ekubuyiseni iidilesi ze-IP zothungelwano lwangaphakathi lwangoku okanye iziteketiso ze-CNAME zemimandla yendawo kusetyenziswa iidilesi zokuphika-impendulo kunye nokuphika-impendulo-iziteketiso zezicwangciso.
