Questions tagged [dns]

DNS is the Domain Name System, a hierarchical, distributed database to map various information together, such as hostnames to IP addresses. The name is also used as a synonym for nameservers, the specific servers delivering the DNS feature. This tag should be used for all issues about configuration of DNS systems or troubleshooting problems in names resolution.
