Whenever you connect to a website, a DNS (domain name system) first turns the domain name (e.g. www.mozilla.org) into an IP address that allows your internet traffic to reach that destination. Typically, your ISP (internet service provider) provides you with a DNS server that your devices use automatically.
Quandocunque tu te connecte a un sito web, un DNS (systema de nomine de dominio) primo muta le nomine de dominio (p. ex. www.mozilla.org) in un adresse IP, que permitte a tu traffico internet de attinger ille destination. Typicamente, tu ISP (fornitor de servicio internet) te forni de un servitor de DNS que tu apparatos usa automaticamente.
