Calculators
8 tools in this category, and none of them send anything off your device. Everything below computes in the tab you already have open.
What is in this category
Section titled “What is in this category”| Tool | What it does | Leaves your device |
|---|---|---|
| Subnet Calculator | Calculate network addresses, broadcast addresses, and host ranges for IPv4 and IPv6 | no |
| VLSM Planner | Plan Variable Length Subnet Masking with optimal allocation and minimal waste | no |
| MTU Calculator | Calculate MTU and header overhead for various network stacks | no |
| Bandwidth Calculator | Calculate transfer times, throughput, and bandwidth requirements | no |
| Cable Calculator | Calculate signal loss for fiber optic and copper cables with TIA standards compliance | no |
| Data Unit Converter | Convert between bits, bytes, and all data size units (SI and IEC) | no |
| Uptime Calculator | Calculate allowed downtime based on SLA uptime percentage | no |
| Network Calculator | Calculate latency, throughput (BDP), and perform IP math operations | no |
The last column is no for every row, which is the whole point of this category: you can work through it on a locked-down network, on a plane, or inside the desktop app with the network off.
