What is TTL?

Explanation:
TTL stands for Time to Live. It is a field in the IP header that determines how long a packet is allowed to live in the network, effectively limiting how many hops it can traverse. With each router the value is decreased by one, and when it reaches zero the packet is dropped to prevent endless looping. This behavior also enables network diagnostics like traceroute, which probes paths by sending packets with progressively higher TTL values. Note that TTL is not about time to login, total time latency, or time to link; it’s about the maximum number of routers a packet can pass through before being discarded. In IPv6 the concept is similar and is referred to as Hop Limit.
