      What happens when a router receives a packet with a TTL of 0?

      Answer: When the router receives a packet with TTL 0f 0, generally it is dabbed by the router and the ICMP TTL is used by it, to send back the packet to its host IP. if the TTL is 0 then the particular packet gets dropped. However, the host sends the packets again and again even all of them not went or reach their destination.in simple words, the packet with TTL 0 sends the ICMP type 11 along with 0 code to the destined IP host.

      What do you know about TTL?

      Time-to-live TTL is the period of the packets of information that is present on the computer before its termination. TTL of the packets depends on the content such as TTL in internet protocol which gives the information to a network router for how long and when the frames exist in the network or computer.

      TTL in networking:

      In the packets, TTL is installed as the timestamp, and when the particular packet time ends, it can either be discarded or revalidated.TTL in networking is to keep the data frames moving indefinitely across the network’s works in an application is to maintain the data cache and the performance boosts. Other uses of TTL are content delivery network cache or DNS caching.

      Working of the TTL:

      The TTL value can be set between two values which are 1 and 255, while the different OS has varied in the default setting. The router will minus 1 from the TTL calculation when the frames are closer or by the router. After it, the frames move toward the next destinated host in a network. After the last subtraction, the TTL count becomes 0, and packets are removed by the router. Which initiates the ICMP (internet control message protocol) message which is moved back to the source host.

      TTL work is also known as a hop limit that keeps the undeliverable frames that are present in the routing loops, possibly due to the incorrect value of the routing tables, which are circulated in the network for a long time and make the network clogging.

      In MPLS (Multiprotocol label switching protocol) clouds, its TTL is a copy of IP TTL at the entering of the frames in the clouds. When the packets leave the MPLS TTL value is also copied to the IP TTL field in case the value is less than the value in the IP TTL field.

      If you want to increase the lifetime of the data frames, TTL comes in handy by determining the time of the packet’s circulation and its time for how long it can move in the network. This will give the sender details about the paths of the frames across the internet.

      Use of the TTL in different fields:

      Some of the TTL uses are mentioned below:

      • TTL is used for caching information for a fixed period.
      • CDNs use the TTL to find the period of the cached content to be served from the CDN server.
      • TTL is used by DNS to determine the time of DNS cache server might serve a DNS record.
