Optimized for AWS, Azure, and GCP network planning with special features for cloud subnet calculations.
All calculations happen in your browser - your network details never leave your device.
Created by network engineers for developers, with binary notation and detailed subnet information.
Calculate network address, broadcast address, usable IP range and more
A subnet calculator is an essential networking tool that helps you determine various parameters of your IP networks. When you input an IP address and subnet mask (or CIDR notation), the calculator provides crucial information about your network.
Our calculator also includes special features for cloud environments, helping you account for reserved IPs in AWS networks and plan your cloud infrastructure more effectively.
Proper subnet planning is crucial for:
Whether you're designing a new cloud architecture, configuring a container network, or planning your home lab, our subnet calculator provides the precise information you need for successful network implementation.

A subnet calculator is an assistant that helps you determine various network parameters from an IP address and subnet mask. It's important for:
Input your base IP address (e.g., 192.168.1.0) into the calculator's IP address field.
The mask can be selected from the available formats using the dropdown menu:
255.255.255.0)/24)If the answer is yes, select the 'Calculate for AWS Network' checkbox.
The calculator will display important network information:
Let's calculate a subnet for a small office network:

This subnet calculator is designed to assist developers, DevOps engineers, network engineers, IT professionals, Cloud Architects, and software engineers in configuring their cloud networks. It's also readily available for anyone who needs to perform subnet calculations.
Created by a Network Cloud Engineer with over 15 years of experience. This tool is designed based on classic networking fundamentals, although the output has been adapted for compatibility with some public cloud providers.
I guess that it is self-explained but let me goTo utilize an IP subnet calculator, I simply input the network address and subnet mask. The calculator then outputs relevant subnet information such as the usable IP address range, number of subnets, number of hosts per subnet, network address, broadcast address, subnet mask, wildcard mask, and IPv4 APR domain.
Yes, this calculator can be used in cloud environments. The networking concepts and subnetting principles generally apply. However, you need to consider some reserved IP addresses that may differ in cloud environments.
To calculate the subnet mask, you need to determine the number of bits required for the network portion and the remaining bits for the host portion. The formula to calculate the subnet mask is 2^n - 1, where n is the number of bits in the network portion. For example, if you have 3 bits for the network portion, the formula would be 2^3 - 1 = 7, which means the subnet mask would be 255.255.255.248.
Subnetting is fundamentally rooted in binary. Displaying the binary representation of IP addresses and subnet masks helps you visualize how subnets are represented in the way computers store and process information using binary code (1s and 0s).
Technically, a subnet mask is a 32-bit number used to divide IP addresses into two parts: network and host addresses. The first part identifies the network to which the device belongs, while the second part identifies the device itself within that network.
Better IP allocation by dividing a large network into smaller subnetworks. Better network performance by reducing the number of broadcast domains and their size. Improved security by limiting the scope of potential attacks.
