[comp.protocols.tcp-ip] traceroute & record-route

guyton%condor@RAND.ORG (12/18/89)

While traceroute is pretty good for figuring paths from A to B, it's
useless for figuring out the return paths unless you can invoke it
again from B.

Record route is almost useless because there is only room for six
addresses in the IP header.  This was ok during the days when each
"network" was the size of ARPANET or MILNET, but with a network id
(and route) for each T1 line on the current internet, the first six
addresses usually don't tell you very much.
