What happens to an IP datagram when its TTL reaches 0?

what happens to a packet if the TTL field reaches 0 I dont believe a datagram reaches O because once the datagram reaches 1 the router or device discards it.I banged ur mom she sucked this stick B-----D


What does the TTLvalue zero indicate?

The TTL (Time To Live) value is a number associated with network routing packets. An information packet will only be forwarded to a certain number of routers before the packet is dropped (deleted). The TTL is a counter decreased by 1 when the packet is forwarded to another router. When the TTL reaches zero, it will not be forwarded to another router.

How TTL is operating?

TTL (Time to Live) is reduced by 1 every time a router forwards the packet. The purpose of this is to reduce the negative effects of routing loops. If two routers are misconfigured (it happens) and send a packet back and forth to each other assuming the other router will take care of it, the packet would simply never go away, if it wasn't for TTL. It guarantees that this can only happen a maximum of 256 times (generally quite a bit less). Once that TTL reaches zero, the packet is discarded.

How does ttl shutdown work?

TTL (Time To Live) shutdown is a feature that automatically terminates a connection if the TTL value (which represents the maximum number of hops a packet can traverse) expires. This helps prevent indefinite looping or other issues that can occur if a packet does not reach its destination. Once the TTL value reaches 0, the connection is forcibly closed to ensure network stability and security.


Which field of ip address is changes from router to router?

The TTL will be reduced by one every time it passes a router. Because this changes the IP header, the checksum also has to be recalculated.The TTL will be reduced by one every time it passes a router.

What is the purpose of TTL field in ip header?

It's a time-to-live field designating that the packet is OK to forward from one device to another for a certain amount of time. If the packet gets caught in a routing loop, it won't just go back and forth forever. If that were allowed to happen, many other packets would be doing the same thing, just being mis-routed back and forth between the confused devices, until the available bandwidth on the link was saturated. The TTL assures that the packet will not be forwarded by the very next routing device that reads the packet's TTL field and sees that its TTL has expired. The packet would be discarded at that point.


Why when you ping a host in a LAN the TTL value is 128 but if you ping a host in another network the TTL value decreases from 255 to 254 my question is why the TTL value is 128?

The TTL or Time To Live is a value used to make packets eventually die, so they don't end up in infinite loops, clogging the network over time. Certain network devices decrement this value (routers mainly) by one as they process it. When the TTL reaches zero, the packet is discarded. Each Operating System implements its TCP/IP stack differently and starts packets off with the TTL of their choosing (the default TTL of the stack can be changed, but rarely is). Windows is 128 Linux is 64 Cisco is 256 So if your TTL is around 128 (remember the TTL gets decremented by certain devices) you are PROBABLY pinging a windows box. If it's near 256, probably Cisco etc. You can't rely on this information because other network devices can rewrite the TTL in a packet, but it's a decent indication of the OS on the other end, especially if it's a box you own and you aren't going through firewalls etc.


Why the ttl change in the same ping?

The TTL (Time to Live) value in a ping packet decreases by 1 each time it passes through a router. This helps prevent packets from circulating endlessly in a network. When a TTL reaches 0, the router discards the packet and sends an ICMP Time Exceeded message.
