IP Subnet Calculator – Calculate subnet masks, host ranges, and CIDR notations for IPv4/IPv6 networks.
The IP Subnet Calculator helps calculate network subnets, ranges, and masks for both IPv4 and IPv6 addresses. It is an essential tool for network administrators, IT professionals, and cybersecurity experts to optimize IP address allocation and improve network efficiency.
✅ Subnet mask, wildcard mask, and prefix length (/CIDR)
✅ Network ID, broadcast address, and usable host range
✅ Number of hosts per subnet
✅ Efficient division of IP address space
Works with IPv4 and IPv6 addresses
Provides detailed subnet information instantly
Prevents IP conflicts and wasted address allocation
Supports both classful and classless addressing
📌 Network administrators planning IP distribution
📌 IT students learning subnetting concepts
📌 Cybersecurity professionals managing secure networks
📌 Companies organizing large-scale IP address blocks
Subnetting reduces network congestion and security risks by dividing large networks into manageable smaller networks.
