Thanks.
That seems to be the simplest method suggested so far:
----------------------------------------
[tim at althea ~]$ traceroute -n google.com
traceroute to google.com (74.125.45.100), 30 hops max, 40 byte packets
 1  192.168.1.1  1.049 ms  1.279 ms  1.566 ms
 2  192.168.100.1  27.415 ms  30.226 ms  32.609 ms
 3  88.45.2.33  36.093 ms  38.530 ms  41.458 ms
----------------------------------------
[tim at rose ~]$ ping -c2 88.45.2.33
PING 88.45.2.33 (88.45.2.33) 56(84) bytes of data.
64 bytes from 88.45.2.33: icmp_seq=1 ttl=238 time=102 ms
----------------------------------------
Seems to work too ...
