go implementation of ipcalc
A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination.
Handy little script for reconciling IP Addresses to CIDR ranges - input/output CSV or CLI.
Intelligently creates a redundant VPC network across availability zones with subnets gateways and routes to house any service eco-system.
Provides helper (extension)methods for working with IPNetworks
A modern, object-oriented TypeScript library for representing and performing arithmetic on IP addresses and subnets.
CIDR to IP range converter is an online tool that helps you convert CIDR notation into a list of individual IP addresses that are part of the specified range
Browser-based IPv4 subnet calculator (React + TypeScript) with CIDR details, subnet splitting, VLSM planner, overlap checker, binary view, history and JSON/CSV export. Runs fully client-side.
