What is DNS Resolution?

DNS (Domain Name System) converts hostnames to IP addresses, enabling users to access websites without remembering numeric addresses. Linux systems use /etc/resolv.conf to configure DNS resolution. Applications consult the DNS resolver, which communicates with DNS servers for address translation. Use nslookup or dig commands to query DNS and troubleshoot network connectivity issues.
