About taap.digital

taap.digital is a collection of free calculators for people who design, build and operate networks: network engineers, sysadmins and CCNA/CCNP students. Each tool shows the result and the math behind it, so you can check the reasoning instead of trusting a black box.

What you will find

• IPv4 subnetting, VLSM planning, route summarization, range-to-CIDR and wildcard masks.
• IPv6 prefix planning.
• Throughput tools: transfer time, data-rate conversion and the TCP bandwidth-delay product.
• Infrastructure budgets: PoE power and fiber optic loss.

The site is available in English, Portuguese and Spanish. All calculations run locally in your browser.
