Not talking about ping. There is a difference between ICMP listening
for echo reply (ping) and measuring the TTL decreasing to figure out
which hosts your data is being routed through (traceroute). Has to do
with the different control pit set in the packet that determines which
kind of ICMP diagnostic you're sending/listening for.
