Cada cop que afegim un domini a la barra d’un navegador, o fem clic en un enlla\u00e7, es genera una petici\u00f3<\/strong> que passa per diversos llocs abans de portar-te a la web on vols. En aquest proc\u00e9s trobem els servidors de DNS, que s\u00f3n molt importants.<\/p>\n

DNS \u00e9s l’acr\u00f2nim de (Domain Name System) o (Sistema de Nom de Domini). Aix\u00f2, a grosso modo, serveix perqu\u00e8 puguem posar articagency.cat o www.google.com en un navegador i que ens acabi mostrant la web que volem.<\/p>\n

Els servidors de DNS s’encarreguen de \u201dtraduir\u201d la petici\u00f3 del nom de domini per l’adre\u00e7a IP del servidor on es troba el lloc web i poder portar la petici\u00f3 de l’usuari a la seva destinaci\u00f3. La resposta t\u00e8cnica \u00e9s m\u00e9s complexa, per\u00f2 per entendre-ho d’una manera b\u00e0sica seria una cosa similar.<\/p>\n

Per qu\u00e8 Tarden a Propagar-se les DNS?<\/h2>\n

Si mai es fa un canvi de DNS en un domini, aix\u00f2 implica que apuntar\u00e0 a un altre servidor de DNS i ser\u00e0 aquest servidor el que indiqui a quina adre\u00e7a IP cal mirar i quina web mostrar.<\/p>\n

Aquest canvi pot trigar a fer-se diverses hores, o fins i tot m\u00e9s de 24 hores en alguns casos.<\/p>\n

Aix\u00f2 ve donat perqu\u00e8 les empreses que ens subministren Internet (IPS) com Movistar, Orange, etc\u2026 emmagatzemen a la mem\u00f2ria cau les dades de tots els servidors DNS del m\u00f3n per accelerar el tr\u00e0nsit i estalviar recursos.<\/p>\n

Per qu\u00e8 tarden a mostrar-se els canvis a la cache?<\/h2>\n

Aix\u00ed doncs, quan es fa un canvi de DNS en un domini, aquest canvi no es reflecteix fins que totes aquestes dades s\u00f3n actualitzades a cadascun dels prove\u00efdors d’Internet.<\/p>\n

El temps en qu\u00e8 triguin a netejar la mem\u00f2ria cau per actualitzar les dades dependr\u00e0 de la pol\u00edtica interna de cadascuna d’aquestes empreses, ja que no \u00e9s una cosa estandarditzada.<\/p>\n

Per a una propagaci\u00f3 completa per tots els servidors de DNS del m\u00f3n podrien passar fins a 2 dies. Tot i que en general, solen estar propagades en unes hores.<\/p>\n","protected":false},"excerpt":{"rendered":"
