IP Range Calculator (Learn While Calculating)

🔗 Live Tool: https://giriaryan694-a11y.github.io/Ip-Range-Calculator/

This webpage helps you understand and calculate IPv4 address ranges using simple math and clear explanations. It is designed for learners, pentesters, and networking beginners who want to see how IP ranges actually work instead of memorizing formulas.

🚀 What This Tool Does

• Accepts range‑based IPv4 input like:

  10.10.0-255.101-125
  

• Explains how IPv4 octets work (0–255)

• Calculates total number of IP addresses in the given range

• Breaks down which octets change and why

• Shows step‑by‑step explanation in simple language

• Includes a “View Possible IPs” button to list all generated IPs

🧠 Why This Tool Is Useful

Most subnet calculators only give answers.

This tool focuses on understanding:

• Why an octet can only go from 0 to 255
• How ranges like 0–255 explode in size
• How attackers and defenders think before scanning
• How tools like Nmap interpret IP ranges

Perfect for:

• TryHackMe / Hack The Box learners
• Junior Pentesters
• Networking students
• Anyone confused by IP math

---

📘 Example

Input:

10.10.0-255.101-125

Explanation includes:

• Which octets are fixed
• Which octets vary
• How many values each range contributes
• Final total IP count

---

⚠️ Note

Very large ranges may generate thousands of IPs. Use the View Possible IPs feature carefully to avoid browser lag.
