Scan IP ranges to find DNS resolvers that work with your server. Read more...
This tool scans IP ranges to find DNS servers that can reach your thefeed server. Enter CIDRs (like 192.168.1.0/24) or individual IPs, pick a profile, and hit Scan. The app sends a small test query to each IP. If the IP answers correctly, it is a working resolver. You can also turn on "Expand /24" — when a working IP is found, the app will automatically check nearby IPs in the same network. Results show response time so you can pick the fastest ones. You can pause, resume, or stop the scan at any time. Show less
