dnspython

This program measures the DNS resolution time for any valid DNS resolvers.

• Number of Queries: 5000 resolvable queries per resolver.
• Sample Query Source: Domain lists from OpenDNS's public domain list:
  OpenDNS Random Domains

Getting Started

1. If using the custom resolver, resolver.py, start the resolver script.

   $ python3 resolver.py port [+enhanced args]

2. In the performance.sh script:
   • Ensure the -rd flag is enabled for public DNS testing.
   • Otherwise, leave the script as is.
3. Run the performance.sh script and enter resolver IP and port number. Example with Google DNS: If testing with Google DNS (IP: 8.8.8.8, Port: 53), provide the following inputs when prompted:

Enter resolver IP: 8.8.8.8
Enter port number: 53

5. The shell script will generate three output files per resolver:
   • [resolver_ip]_raw.txt: Contains raw numerical data.
   • [resolver_ip]_data.csv: Contains domain names and resolution times.
   • [resolver_ip]_response.txt: Parsed output with detailed resolver responses.
