Network Tools Calculator
Comprehensive network calculator for subnet calculations, bandwidth estimation, and VLSM planning. Calculate IP ranges, transfer times, and design efficient network layouts.
Step 1 of 6
How to Use This Calculator
- Select the Tool Type: Subnet Calculator for IP/CIDR analysis, Bandwidth Calculator for transfer time, or VLSM Planning for multi-subnet design.
- For subnet mode, enter the four IP Address Octets (e.g., 192.168.1.100) and the CIDR Prefix length (e.g., 24 for a /24 network).
- For bandwidth mode, enter the Data Size and unit (MB/GB/TB), your Bandwidth in Mbps or Gbps, and Link Efficiency percentage.
- For VLSM mode, set the Starting Network CIDR and enter the required host counts for up to four subnets.
- Review the results: Network Address, Broadcast Address, Usable Hosts, or Transfer Time depending on the selected mode.
- Consult the comparison tables for common subnet sizes or bandwidth across connection types.
