The ability to view the DNS resolver cache, typically achieved through a command-line utility on desktop operating systems, is often unavailable directly on Android. This functionality allows users to inspect the cached DNS records on their device. For example, on Windows, the `ipconfig /displaydns` command achieves this. While Android does not natively offer a directly equivalent command, the intent remains to examine the entries stored by the systems DNS resolver.
Examining the DNS cache provides several benefits, including troubleshooting network connectivity problems and verifying DNS propagation after changes to domain records. Historically, this level of network diagnostics was primarily accessible on desktop platforms, leaving mobile users with less visibility into their device’s network behavior. Understanding the contents of the DNS cache can provide valuable insights into how a device is resolving domain names, aiding in diagnosing resolution issues.
