IP Range Calculator
NewCalculate comprehensive subnet information from CIDR notation (e.g., 192.168.1.0/24). Displays network address, broadcast address, subnet mask, wildcard mask, usable host range, and total host count. Also converts between CIDR prefix length and dotted-decimal subnet mask. Essential for network administrators, DevOps engineers, firewall rule configuration, and cloud VPC/subnet planning.

Frequently Asked Questions
What is CIDR notation?
CIDR (Classless Inter-Domain Routing) notation combines the IP address and subnet prefix length: 192.168.1.0/24 means the first 24 bits are the network, leaving 8 bits for hosts (254 usable).
