TraceNet – Network Bottleneck Analyzer

TraceNet is a command-line Java-based tool that analyzes network paths to detect slow or bottleneck hops using traceroute. It parses each hop's IP and latency using regex and maps them to real-world geo-locations (like city, country, organization) using a public API.

---

🚀 Features

• Performs real-time traceroute to any domain/IP.
• Extracts hop-wise IP and latency details using regex.
• Uses public API to map IPs to geo-locations (e.g., "Sydney, Australia (Google International, LLC)").
• Identifies the bottleneck hop with the highest latency.
• Saves a full hop-by-hop trace report to a .txt file.

🛠 Tech Stack

• Java (Core Java)
• Regex (for IP and latency extraction)
• OS-level command execution using ProcessBuilder
• ip-api.com for IP-to-location mapping
