Subnet Calculator

Subnet Calculator simplifies the complex calculations required to divide a range of IP addresses into smaller networks (subnets).

• CIDR Support: Enter an IP along with a subnet mask (e.g., /24) to calculate the entire range.
• Network Details: Instantly outputs the Network Address, Broadcast Address, First Usable IP, and Last Usable IP on screen.
• Hosts Count: Tells you the maximum number of devices (computers/phones) that can connect to this subnet.

Essential for cloud engineers (AWS/Azure) and network architects configuring VPCs and routers.
