Traceroute is fine for casual analysis but it is inaccurate and/or incomplete for anything serious because it misses routers that use load balancing on packet headers.

This looks neat. Do you know what specifically it does differently than the traditional one? The blurb is vague and the "learn more" link is dead.

There is also the paper that introduced it at https://paris-traceroute.net/images/imc2006.pdf

Akamai uses something similar to perform trace routes in-band of HTTP TCP sessions to clients: https://datatracker.ietf.org/meeting/94/materials/slides-94-...

while the as_number->as_name lookup is usefull i would have opted for adding this feature to one (or more) of the existing utilities (traceroute, mtr, paris-traceroute) instead of crafting yet another command.

FWIW:

  $ traceroute -A ...

  $ mtr -z ...

just stumbled across: https://www.dublin-traceroute.net > Dublin Traceroute uses the techniques invented by the authors of Paris-traceroute to enumerate the paths of ECMP flow-based load balancing, but introduces a new technique for NAT detection.

There are also Python bindings [0] for dublin-traceroute which allows things like analysis with pandas or generating charts.

Try the "about" link at the top.

Ah, wasn't showing up on mobile

-A gets you the AS, my tool looks up the name. So you can see "Oh, it goes from Comcast, to Cogent to Google." cool. Rather than ASNs which you don't immediately recognize.

mtr -z? I mean, it is a good learning effort, but if someone doesn’t know about mtr, they should: https://bitwizard.nl/mtr/

-z only shows AS numbers, not names. The point of this is to quickly tell you companies and networks you recognize. Also, mtr requires sudo to run.
