DNS Management
DNS Management refers to the administration and configuration of the Domain Name System (DNS), which translates human-readable domain names (like example.com) into machine-readable IP addresses (like 192.0.2.1). It involves tasks such as creating, updating, and deleting DNS records (e.g., A, CNAME, MX) to control how traffic is routed to servers, websites, and services. This is essential for ensuring reliable and efficient internet connectivity, load balancing, and security for online applications.
Developers should learn DNS Management when building or maintaining web applications, cloud infrastructure, or distributed systems to ensure proper domain resolution, reduce downtime, and implement features like failover or CDN integration. It is critical for DevOps and site reliability engineers to manage DNS records during deployments, migrations, or scaling events, as misconfigurations can lead to service outages or security vulnerabilities such as DNS hijacking.
