How to Use This Calculator
  1. Follow the step-by-step wizard — complete each step before moving to the next. This guided approach ensures you provide all the necessary information in a logical order.
  2. Tool Type — Calculation mode to use. Choose from: Subnet Calculator, Bandwidth Calculator, VLSM Planning. default: 0.
  3. IP Octet 1 — First octet of the IP address. Accepts values from 0 to 255 (default: 192).
  4. IP Octet 2 — Second octet of the IP address. Accepts values from 0 to 255 (default: 168).
  5. IP Octet 3 — Third octet of the IP address. Accepts values from 0 to 255 (default: 1).
  6. IP Octet 4 — Fourth octet of the IP address. Accepts values from 0 to 255 (default: 100).
  7. CIDR Prefix — CIDR notation subnet mask prefix length. Accepts values from 0 bits to 32 bits (default: 24 bits).
  8. Data Size — enter a numeric value. Accepts values from 0.1 to 100,000 (default: 1,000).
  9. Size Unit — enter your preferred option from the dropdown. Choose from: MB, GB, TB. default: 0.
  10. Bandwidth — enter a numeric value. Accepts values from 0.1 to 100,000 (default: 100).
  11. Bandwidth Unit — enter your preferred option from the dropdown. Choose from: Mbps, Gbps. default: 0.
  12. Starting Network CIDR — enter a numeric value. Accepts values from 8 to 30 (default: 24).
  13. Subnet 1 Hosts Needed — enter a numeric value. Accepts values from 0 to 10,000 (default: 50).
  14. Subnet 2 Hosts Needed — enter a numeric value. Accepts values from 0 to 10,000 (default: 25).
  15. Subnet 3 Hosts Needed — enter a numeric value. Accepts values from 0 to 10,000 (default: 10).
  16. Expand "Advanced Options" for additional fine-tuning. These optional inputs let you model more specific scenarios:
  17. Link Efficiency — Typical: 70-90% of rated bandwidth. Accepts values from 10 % to 100 % (default: 80 %).
  18. Subnet 4 Hosts Needed — enter a numeric value. Accepts values from 0 to 10,000 (default: 5).
  19. Once all inputs are set, review your results in the Results panel. Here's what each output means:
