### casually decided to expound upon "David G. Andersen" <dga@lcs.mit.edu>,
### William Allen Simpson <wsimpson@greendragon.com> the following thoughts
### about "Re: scripts to map IP to AS?":
MJV> Dave (and anyone that downloads lookup_as.c),
MJV>
MJV> Grab a newer version of traceroute.c -- There is a CLASSFULL piece of code
MJV> within the 2.9.3 code-base used in lookup_as.c. The newer traceroute.c
MJV> code removes the 192/8 & 128/8 testing. This is a cut-n-paste from the
MJV> newer traceroute-nanog-6.3.0/traceroute.c. It can be cut-n-pasted into
MJV> your code...
Just a reminder to everyone who intends to query the IRR/RADB... Please be
nice to the RADB whois server and don't DoS it. Open a persistant
connection instead of one for each prefix lookup. For RADB and any other
IRR server running IRRd, this can be accomplished by sending a "!!" in the
beginning and keeping the connection open on your end in a seperate thread
or something that you then issue the query to. For RIPE Whois based IRR
servers, use the "-k" flag.
