IP Subnet Calculator Information & Guide
What is IP Subnet Calculator?
An IP Subnet Calculator is a powerful network planning tool that helps network administrators and engineers calculate various subnet parameters for both IPv4 and IPv6 networks. It automatically computes network addresses, broadcast addresses, subnet masks, host ranges, and other critical networking information.
Subnetting is the process of dividing a larger network into smaller, more manageable sub-networks (subnets). This practice improves network performance, enhances security, and enables more efficient use of IP address space. Our calculator supports both traditional classful networking and modern CIDR (Classless Inter-Domain Routing) notation.
Whether you're designing a new network infrastructure, troubleshooting connectivity issues, or planning IP address allocation, this calculator provides accurate and comprehensive subnet analysis for professional network management.
Key Features
- IPv4 and IPv6 subnet calculations with full parameter analysis
- Support for all network classes (A, B, C) and CIDR notation
- Automatic calculation of network, broadcast, and host addresses
- Binary and hexadecimal representation of subnet masks
- Export results to CSV for documentation and reporting
