This Python script is designed to gather information about a list of domains.

About | Output | Screenshot | Download & Install | How to use

The script collects various details about each domain, or rather domain names in the first column of input.csv including:

• IPv4
• IPv6
• Autonomous System Number (ASN)
• ASN organization
• ISO code of the country
• Country name
• Cipher
• SSL/TLS version
• Issuer organization
• Ping response time from the domain's server

The results are saved in a SQLite database named output.db and a CSV file named results.csv. An example is provided below:

• It is strongly recommended to use PyPy 3.10 instead of the official Python interpreter for significantly better performance.
  • Download Links: https://www.pypy.org/download.html
• After configuring the pip module or virtualenv (optional), you need to install the required modules from requests.txt
  • Official document: https://doc.pypy.org/en/latest/install.html#installing-more-modules

• Run main.py as the starting point; then you will be asked a series of questions.
• As the first question, you must declare how many of the available domain names in the input.csv file you want to choose.

• Active tasks (Semaphore) defines a boundary for active tasks at the moment.
• Max workers should be double of the number of active tasks, for example if the number of tasks is 100, the number of workers should be 200, but the default value (auto) is calculated using this approach (Python document): "Changed in version 3.8: Default value of max_workers is changed to min(32, os.cpu_count() + 4). This default value reserves at least 5 workers for I/O-bound tasks. It utilizes at most 32 CPU cores for CPU-bound tasks which release the GIL. And it avoids implicitly using very large resources on many-core machines."

• Ping timeout | TLS info timeout (DNS Connection) | Task timeout

• You can update the database every few days to get the latest and most up-to-date changes.
• You can find the result.csv in the csv directory.
