⚡ DNS Latency Optimizer

A simple Python tool to check which DNS server is fastest for your internet.

---

📖 What This Tool Does

When you open a website, your system first asks a DNS server to get the IP address.

Some DNS servers are slow. This tool:

• Checks many DNS servers
• Measures their speed (latency)
• Shows which one is fastest for you

---

🚀 Features

• ⚡ Fast checking using multithreading
• 🌐 Real network test using TCP (port 53)
• 📊 Clean and easy-to-read output
• 🏆 Shows fastest DNS automatically
• 📁 Saves results in CSV file

---

🛠️ Requirements

• Python 3 installed
• No extra libraries needed

---

▶️ How to Run

Step 1: Download the code

git clone https://github.com/gaikwad-kunal/DNS-Optimizer.git
### Step 2: Go to folder

cd DNS-Optimizer
### Step 3: Run the script

python network_monitor.py

📊 Sample Output

Below is how the output looks:

🏆 Final Result

After running, you will see something like:

🏆 Fastest DNS: Quad9 (9.9.9.9) → 2.17 ms

This means:

• Quad9 is the fastest for your network.
• You can use this DNS in your system/router.

📁 Output File

The tool also saves results like this: dns_results_YYYYMMDD_HHMMSS.csv

You can open it in Excel.

💡 How to Use Fast DNS

After finding the fastest DNS:

1. Open Network Settings
2. Change DNS manually
3. Add the fastest IP (example: 9.9.9.9)

🧠 Use Cases

• Faster website loading
• Better gaming ping
• Network testing
• Learning networking

📬 Note

• Speed depends on your location
• Run the tool multiple times for accuracy
• Fastest DNS may change
