DNS Tools is a free network troubleshooting app developed by whites11 for Android devices. It is a comprehensive app that allows you to troubleshoot and monitor your local area network (LAN) and resources on the web. With DNS Tools, you can get information about your device's mobile and Wi-Fi connections, including IP address, gateway, DNS servers, and netmask. You can also get your current public IP address using ipify.org.

The app also offers the ability to ping any local or remote host by name or IP address and get basic real-time statistics about the ping results, including average ping time and percentage of success. Additionally, you can query a DNS server for a name and specify which DNS server to query and which record types to query (it actually supports A, CNAME, TXT, MX, and NS records). Lastly, you can query the main root DNS servers for a record, which is useful to monitor DNS propagation.

DNS Tools comes with history support to get fast access to repetitive tasks. It is an excellent app for anyone who needs to troubleshoot their network or monitor their resources on the web.
