Q: Computer 1 on network A, with IP address of 10.1.1.8, wants to send a packet to Computer 2, with IP address of 172.16.1.64. If the TTL value was set to 64 at the beginning, what is the value of the TTL once it reaches its destination?

Q: With an IP address of 10.1.1.8, Computer 1 on network A wishes to transmit a packet to Computer 2, which has an IP address of 172.16.1.64. When a TTL value reaches its destination, what value does it change from its initial setting of 64?
- 65
- 60
- 0
- 62
Explanation: TTL, which stands for “Time-to-Live,” is a field in the Internet Protocol header that is decremented by one whenever a packet passes through a router. Specifically, the starting TTL value is 64 in this instance. Each time a packet travels through a router, the time-to-live (TTL) value is decreasing by one. Due to the fact that the packet is moving from Network A to Network C, it will go via Router Z. Since this is the case, the TTL will be reduced by one when it travels via Router Z.
