TTL Decoder 🕒

TTL Decoder is a free, fast-loading tool designed for IT professionals, network engineers, and security analysts. It helps decode Time-To-Live (TTL) values captured from traceroute, ping, or packet capture tools and determines the likely initial TTL based on known defaults across major operating systems.

🔍 How to Use

1. Enter any valid TTL value (1–255) observed in a network packet.
2. The tool will identify the closest matching initial TTL.
3. It displays the estimated originating OS and how many router hops the packet has taken.

Use Cases:

• 🎯 OS fingerprinting (e.g., guess if a host is running Windows or Linux).
• 📡 Understand routing paths and optimize network paths.
• 🛡️ Forensics and threat hunting in network analysis.
