astraceroute on MAC

Fri Oct 10 20:45:43 UTC 2014

Dear Tim and Niels

Surely default traceroute in MAC is there but the -a option isn't good. It
picks data from RADB and not from actually visible prefix in global routing
table. Hence wrongly registered RADB objects / old objects and more give
weird output.

E.g take example of trace to one of AS10029's IP's (the company I work
for...)

traceroute to 203.122.59.75 (203.122.59.75), 30 hops max, 60 byte packets

Here I am getting  203.122.61.148.reverse.spectranet.in (203.122.61.148)
[AS10029/AS7722] in 9th hop. Now prefix is announced by AS10029 only but it
shows AS7722 as well because there's a route object in RADB from Rivernet
AS7722 in 2006.

route:      203.122.61.0/24
descr:      Rivernet
origin:     AS7722
mnt-by:     MAINT-AS7474
changed:    noc at optus.net.au 20060120
source:     RADB

I wish to see origin ASN of a prefix which is why looking for that tool.

Thanks.
