Re: Traceroute

I am not sure about this, but as far as i know, record route is not a
mandatory directive according to standards, and routers are free to
ignore it.

Talking about traceroute, it works by incrementing the ttl by one each
time, so that each packet travels one hop further before being dropped
and an ICMP message coming back to the sender, right? However, IP
itself is designed so that each route is decided when the packet is
transmitted, not like in a VC. Thus, does a traceroute like that make
much of a sense? Since you never know what route your other packets,
or even all packets involved in the trace, took?

pray forgive my foolishness everybody!
