Subject: difference between DROPped pings and non existing hosts

Hi,
I would like to know how ICMP distinguishes between DROPped pings and
non existing hosts. Both times you don´t get a reply from the
destination host but if it doesn´t reply because it doesn´t exist you
get the correct destination unreachable message if it drops the requests
for example with IPTables you get a timeout. And I haven´t a clue why
this is so.
