IP Subnet Calculator (IPv4 Subnet Calculator) – Network Tool

The IP Subnet Calculator is a powerful networking tool designed to help IT professionals, network administrators, and students quickly analyse IPv4 subnets. It provides detailed information about network configurations, including subnet masks, usable host ranges, broadcast addresses, and more.

Key Features

1. IPv4 Subnet Calculations

• Network Address: Identifies the base address of the subnet.

• Usable Host Range: Shows the range of assignable IP addresses.

• Broadcast Address: Determines the broadcast IP for the subnet.

• Total & Usable Hosts: Calculates the number of available hosts.

2. Subnet Mask & CIDR Support

• Supports all standard subnet masks (from /1 to /32).

• Converts between CIDR notation (e.g., /24**) and **dotted-decimal subnet masks** (e.g., 255.255.255.0`).

• Provides wildcard mask (inverse of subnet mask).

3. IP Classification & Properties

• Detects IP class (A, B, C, D, E) automatically.

• Identifies IP type (Public, Private, Loopback, Link-local).

4. Advanced IP Representations

• Binary Subnet Mask: Displays the subnet mask in binary form.

• Integer & Hex Conversion: Converts IP addresses to integer and hexadecimal formats.

• IPv4 Mapped & 6to4 Addresses: Generates IPv6 representations of IPv4 addresses.

• Reverse DNS (in-addr.arpa): Provides the reverse DNS lookup format.

Who Should Use This Tool?

✔ Network Engineers – Plan and troubleshoot subnet allocations.
✔ System Administrators – Configure servers and firewalls efficiently.
✔ Students & Learners – Understand IPv4 subnetting concepts.
✔ Cybersecurity Professionals – Analyze network segmentation.

How to Use?

1. Enter an IPv4 address (e.g., 192.168.1.1).

2. Select a subnet mask (e.g., /24 or 255.255.255.0).

3. Click “Calculate” to view detailed subnet information.
