<\/a>\nLors de DNS Flagday 2019, de nombreux fournisseurs de serveurs et op\u00e9rateurs de serveurs, tels que Google et Facebook, travaillent ensemble pour finalement \u00e9tablir les extensions EDNS.<\/h5>\n
<\/p>\n
Y a-t-il beaucoup de serveurs DNS d\u00e9fectueux ?<\/h3>\n
La r\u00e9ponse claire \u00e0 cette question est : oui, malheureusement ! Parce que beaucoup trop de serveurs r\u00e9pondent \u00e0 une requ\u00eate DNS avec une extension EDNS de mani\u00e8re incorrecte ou pas du tout. Il est donc grand temps d’agir, car cette exigence est \u00e0 l’ordre du jour depuis pr\u00e8s de 20 ans.
\nBeaucoup de gens se demandent probablement pourquoi les serveurs DNS n’impl\u00e9mentent pas correctement l’extension EDNS. Parce que jusqu’\u00e0 pr\u00e9sent, tout a fonctionn\u00e9, parce que les prestataires ont simplement \u00e9vit\u00e9 le probl\u00e8me au moyen de certaines m\u00e9thodes, appel\u00e9es solutions de contournement.
\nIl y a aussi une r\u00e9ponse claire \u00e0 cette question, car d’une part ces solutions de contournement co\u00fbtent toujours beaucoup de travail car elles doivent \u00eatre d\u00e9velopp\u00e9es sp\u00e9cialement. Cela complique inutilement le logiciel DNS. D’autre part, les solutions de contournement co\u00fbtent aussi beaucoup de temps. Non seulement dans le d\u00e9veloppement et la programmation, mais surtout dans le cadre des requ\u00eates DNS.<\/p>\n
<\/p>\n
Quels changements concrets y a-t-il maintenant ?<\/h3>\n
Le DNS Flagday n’attire pas seulement l’attention sur le probl\u00e8me et donne un signal de mise \u00e0 jour aux extensions EDNS, mais aussi sur les changements qui prennent effet. Knot, un logiciel DNS bien connu, a d\u00e9j\u00e0 supprim\u00e9 toutes les solutions de contournement et les programmes Unbound, Bind et PowerDNS suivent avec les versions suivantes.
\nEn outre, les partisans du DNS flagday, tels que Facebook et Google, mais aussi Cloudfare, font des changements correspondants dans leurs syst\u00e8mes.<\/p>\n

<\/a>
\nDNS Flagday 2019 n’est pas seulement une question de signalisation, mais aussi de changements concrets dans le domaine des serveurs DNS qui sont impl\u00e9ment\u00e9s.<\/h5>\n <\/p>\n
Que devriez-vous faire maintenant ?<\/h3>\n
En tant qu’exploitant d’un site Web, il vous est maintenant conseill\u00e9 de v\u00e9rifier votre serveur DNS. C’est tr\u00e8s simple, car l’initiative fournit son propre site web avec un ch\u00e8que gratuit. Vous pouvez le trouver sur https:\/\/dnsflagday.net\/index-de.html.
\nVotre serveur DNS est probablement fourni et g\u00e9r\u00e9 par un h\u00e9bergeur de votre choix. Beaucoup de ces h\u00f4tes connaissent d’\u00e9normes probl\u00e8mes \u00e0 cause du DNS flagday. Parce que certains serveurs DNS des h\u00f4tes fonctionnent probablement encore avec des logiciels d\u00e9fectueux. Bien que votre domaine continuera \u00e0 fonctionner avec une grande s\u00e9curit\u00e9, les demandes prendront probablement plus de temps. Parce que les h\u00f4tes utilisent plusieurs serveurs DNS, une requ\u00eate demandera plusieurs serveurs jusqu’\u00e0 ce qu’un serveur r\u00e9ponde correctement.
\nLes pare-feu peuvent aussi \u00eatre un probl\u00e8me que vous devriez r\u00e9gler. Par exemple, la v\u00e9rification indique que certains pare-feu bloquent les requ\u00eates contenant des messages EDNS. Par cons\u00e9quent, les fonctions qui bloquent les paquets contenant des messages EDNS doivent \u00eatre imm\u00e9diatement d\u00e9sactiv\u00e9es dans les pare-feu.<\/p>\n","protected":false},"excerpt":{"rendered":"
