CAIDA has lots of data sets, tools, etc. Here's one of the README files I grabbed, with some URLs that would help you find the specifics, and reference materials (papers) on what/why/how they are able to infer these relationships.
Brian The 'serial-2' directory contains AS relationships that combine the > > 'serial-1' AS relationships (inferred using the method described in > > "AS Relationships, Customer Cones, and Validation" published in > > IMC 2013, http://www.caida.org/publications/papers/2013/asrank/), > > with AS relationships inferred from Ark traceroutes, and from > > multilateral peering > > ( > http://www.caida.org/publications/papers/2013/inferring_multilateral_peering/ > ). > > > > To do this we first infer which AS owns each router independent of the > > interface addresses observed at that router. The ownership inferences > > are based on IP-to-AS mapping derived from public BGP data, list of > > peering prefixes from PeeringDB, and the previously inferred business AS > > relationships. Then we convert the observed IP path into an AS path > > using the router ownership information (rather than mapping each > > observed IP to AS directly) and retain the first AS link in the > > resulting path for the AS graph. > > > > The as-rel files contain p2p and p2c relationships. The format is: > > <provider-as>|<customer-as>|-1 > > <peer-as>|<peer-as>|0|<source> > > > ------------------------ > > Acceptable Use Agreement > > ------------------------ > > > > The AUA that you accepted when you were given access to these datas is > included > > in pdf format as a separate file in the same directory as this README file. > > When referencing this data (as required by the AUA), please use: > > > > The CAIDA AS Relationships Dataset, <date range used> > > http://www.caida.org/data/active/as-relationships/ > > > > Also, please, report your publication to CAIDA > > (http://www.caida.org/data/publications/report-publication.xml). > On Mon, Mar 11, 2019 at 4:48 PM Robert Raszuk <[email protected]> wrote: > Dear authors of draft-chen-grow-enhanced-as-loop-detection, > > The draft says: > > " At this point, AS 200 *can lookup the local resource database* and > check whether there is a real AS relationship between the local AS > and the left AS and the right AS" > > Can you please share a pointer to any database or accurate public oracle > where anyone could check if peering relation found in the AS-PATH is valid > or invalid ? > > Just over the last few months I connected my AS to number of Tier1 ISPs in > few of my experimental POPs, but never reported that peering establishment > to anyone.
