PingDNS

PingDNS is a command-line tool for mass pinging DNS servers to measure their latency using ICMP pings. It supports scanning up to 60,000 servers efficiently with multi-threading, configurable ping parameters, and optional geolocation data retrieval via GeoIP.

Features

• Mass ping DNS servers (hardcoded and from public-dns.info)
• Multi-threaded for high performance
• Configurable ping count, timeout, and thread count
• Geolocation support for server location data
• Outputs results to console and dns_results.csv

Installation

1. Clone the repository:

   git clone https://github.com/EdgeOfAssembly/PingDNS.git

2. Navigate to the directory:

   cd PingDNS

3. Build with CMake:

   mkdir build && cd build
   cmake ..
   make

4. Run the tool (requires raw socket privileges):

   sudo ./pingdns [options]

Note: Use sudo or set CAP_NET_RAW capability:

sudo setcap cap_net_raw+ep pingdns

Usage

1. Basic scan: sudo ./pingdns

2. Scan 100 servers with 5 pings each, 500ms timeout, and 8 threads: sudo ./pingdns -n 100 -pings 5 -timeout 500 -t 8

See the man page (docs/pingdns.1) for more examples.
