  A Destination Unreachable message can be sent to the computer that is the source of a packet for any of the following reasons:

  The computer cannot find a route to the destination address.

  Communication with the destination address is administratively prohibited. For example, a firewall prevents delivery of packets to the destination.

  The destination address is unreachable.

  A packet's Hop Limit determines how many times it can be forwarded before it is discarded. Each time a packet is forwarded, its Hop Limit value is decremented by one. When the Hop Limit reaches zero or when a router receives a packet with its Hop Limit set to zero, the packet is discarded and the source of the packet receives a Time Exceeded message indicating that the initial Hop Limit was too small or that the packet was caught in a routing loop.
