Hi James,
Doh! I was thinking of DNS (where ttl is seconds in cache).
from 'man ping':
The TTL value of an IP packet represents the maximum number of IP routers
that the packet can go through before being thrown away. In current
practice you can expect each router in the Internet to decrement the TTL
field by exactly one.
