Скачать или смотреть TTL Explained in TCP/IP | Time to Live, Loop Prevention & Troubleshooting | TCP/IP Series

In this video from my TCP/IP Series, I explain TTL (Time To Live) in detail and show why TTL is one of the most important fields in the IP header.

In this session, you will learn:

• What TTL (Time To Live) is in TCP/IP
• Where TTL is present in the IP header
• How TTL works hop-by-hop across routers
• Why TTL is used to prevent routing loops
• What happens when TTL becomes zero
• How routers decrement TTL and drop packets
• Why Traceroute depends on TTL
• Real-world troubleshooting use cases

This topic is extremely important for CCNA, CCNP, CCIE, Network+, and Cyber Security students who want strong IP-level fundamentals and better troubleshooting skills.
