Hi, bit weird question, but is it possible to determine relationship(Internet transit, settlement-free peering, etc) between the operators based on import and export statements in aut-num object? Often aut-num objects in RIR database contain the remarks which describe such relationships. However, for example here I have following import and export attributes from an aut-num object of an ISP: import: from AS65133 action pref=100; accept ANY import: from AS65798 accept AS65798 import: from AS65084 accept AS65084 import: from AS65485 action pref=100; accept ANY import: from AS65751 accept AS65751 import: from AS65059 action pref=100; accept ANY import: from AS65128 accept AS65128 export: to AS65133 announce AS-SET export: to AS65798 announce ANY export: to AS65084 announce ANY export: to AS65485 announce AS-SET export: to AS65751 announce ANY export: to AS650835 announce AS-SET export: to AS65128 announce ANY Am I correct that it is safe to say that probably AS65133, AS65485 and AS65059 are the uplink providers and AS65798, AS65084, AS65751 and AS65128 are the customers of this ISP? Last but not least, maybe there is altogether a more reliable way to understand the relationship between the operators than aut-num objects(often not updated) in RIR database? thanks, Martin
