In today’s interconnected world, understanding the complex landscape of the internet and its underlying infrastructure has become crucial for many businesses and organizations. Whether it’s for network security, traffic optimization, or competitive analysis, having insights into the various networks and Autonomous Systems (ASes) that make up the internet can provide valuable information. One tool that has gained popularity in recent years for this purpose is ASNMap.
ASNMap is a powerful network mapping and analysis tool that allows users to visualize and analyze the ASes and networks that are part of the global internet routing system. It provides a wealth of information, including AS number, AS name, AS description, country code, and network prefix, among others. ASNMap can be a valuable asset for network administrators, security analysts, and researchers who need to gain insights into internet routing and AS relationships.
Installing ASNMap is a relatively straightforward process. It is a Python-based tool, so users need to have Python installed on their system. Follow these steps to install ASNMap:
Step 1: Install Python: If Python is not already installed on your system, you can download and install it from the official Python website (https://www.python.org/).
Step 2: Install ASNMap: Once Python is installed, open a command prompt or terminal window and use the following command to install ASNMap using pip, the Python package manager:
pip install asnmap
This will download and install ASNMap and its dependencies on your system.
After installing ASNMap, you can start using it to map and analyze networks and ASes. ASNMap provides several functionalities that can be accessed through its command-line interface (CLI). Here are some common use cases and examples of how to use ASNMap:
- Network Mapping: ASNMap allows you to map the networks associated with an AS or a range of IP addresses. To map the networks of an AS, use the following command:
asnmap -a <AS_NUMBER>
<AS_NUMBER> with the desired AS number. ASNMap will query the global routing tables and retrieve information about the networks associated with the specified AS, and then display the results on the screen or save them to a file.
- IP Address Mapping: You can also use ASNMap to map the ASes associated with a specific IP address or a range of IP addresses. To map the ASes of an IP address or a range of IP addresses, use the following command:
asnmap -i <IP_ADDRESS/IP_RANGE>
<IP_ADDRESS/IP_RANGE> with the desired IP address or IP address range. ASNMap will query the global routing tables and retrieve information about the ASes associated with the specified IP address(es), and then display the results on the screen or save them to a file.
- Visualization: ASNMap provides options to visualize the results of network and IP address mapping. You can generate graphical representations of AS relationships and network topologies using the
-goption followed by the output file format (e.g.,
-g pdf). For example:
asnmap -a <AS_NUMBER> -g png
This will generate a PNG image file that represents the networks associated with the specified AS in a graphical format.
- Customization: ASNMap also allows you to customize the output by specifying various options, such as output format, verbosity level, and timeout, among others. You can refer to the ASNMap documentation (https://github.com/besiobu/asnmap) for a comprehensive list of available options and their usage.
