Local DNS
Local DNS is a system that resolves domain names to IP addresses within a local network, such as a home or office environment, without relying on external DNS servers. It allows devices on the same network to communicate using human-readable hostnames instead of numerical IP addresses, often implemented through tools like dnsmasq or built into routers. This setup improves network performance, provides control over name resolution, and can block unwanted domains for security or privacy.
Developers should learn and use Local DNS when setting up development environments, testing network-dependent applications, or managing internal services in a lab or corporate network. It is essential for scenarios like local web development with custom domains (e.g., using 'myapp.local'), creating ad-hoc networks for IoT devices, or implementing network-level ad-blocking to enhance security and reduce distractions during work.
