LanCalculator is a network administration software utility developed by LizardSystems (originally created by LanTricks) that automates the design, analysis, and calculation of IPv4 and IPv6 network subnets. It eliminates the need for manual binary-to-decimal calculations, making it a popular choice for network engineers, IT professionals, and students studying for networking certifications like the Cisco CCNA. Core Capabilities
Dual Protocol Support: Seamlessly analyzes both older IPv4 and modern 128-bit IPv6 networks.
Subnet Parameters Generation: Once you enter a specific IP address and criteria (e.g., prefix length, number of bits, or maximum hosts), it automatically details the exact network IP, host range, and broadcast address.
Local Adapter Detection: Automatically identifies the network cards on your current machine to fetch your local active IP configurations.
Data Conversion: Displays and converts IP addresses across multiple formats including binary, decimal, octal, and hexadecimal.
Cisco Equipment Mapping: Calculates inverse network masks (wildcard masks) required for configuring Access Control Lists (ACLs) on Cisco routing systems.
Data Export: Allows users to quickly save generated lists of networks and parameters directly to a text file or copy them to the system clipboard. Supported Operating Systems
The latest software iterations (including version 22.01) are optimized for x64 architecture and run natively on the following platforms: Windows 11 Windows 10 Windows Server (2012R2, 2016, 2019) Licensing and Availability
The desktop software is available directly via the LizardSystems Download Page. While commercial deployment requires a paid license after a 30-day evaluation, LizardSystems provides a free registration code for personal, non-commercial use through their Personal License Registration Form.
Are you planning to use it for troubleshooting a specific local network, or are you studying for an IT certification? I can provide concrete subnetting examples or cheat sheets if needed. LanCalculator – IP Subnet Calculator for IPv4/IPv6 Networks
