How to generate random IPv4 address?
Introduction
Every computer connected to the Internet is assigned a unique IP address, which serves as its identifier within the network. The most widely used format, particularly for IPv4, expresses this address as four numerical values ranging from 0 to 255, separated by dots - for example, 192.168.0.1.
This format is not arbitrary - it reflects a 32-bit binary representation of the IP address, segmented into four 8-bit octets. Each segment can represent any number between 0 and 255, enabling a total of over 4 billion unique IPv4 addresses globally. Despite this large number, IPv4 address space has become increasingly scarce due to widespread device connectivity.
A list of IPv4 addresses can be particularly valuable when conducting tests on security systems, access filters, or routing behavior. For instance, developers and administrators might simulate access from various IPs to ensure that firewalls, authentication systems, or geo-blocking mechanisms respond as expected.
In such contexts, having structured and controllable sets of IP addresses facilitates systematic validation of network behavior, making them an essential tool in the toolkit of network engineers and security testers.
