You only *think* you are joking. I still remember the Day of the Great
Restart when everyone on the ARPAnet had to shut down the IMPs and TIPs,
and reload the control software. Why? There were literally thousands
of rogue packets flying around the net, eating up bandwidth (and in
those days, we are talking 56 kbps links!) and boy were those
tubie-thingies plugged up!
Shortly after that cusp event, per-packet TTL field was added to the NTP
protocol, which is why TCP/IP has the TTL field in the IP packet.
The network had added to it a self-cleaning function. Think of it as
one long continuous sneeze.
