AS with `route`s/`route6` but no `aut-num` #76

Closed SichangHe closed 2 months ago

SichangHe commented 8 months ago

In #57, we have 78951 aut-nums, but also 87534 "AS Routes", route/route6 objects grouped by the ASes they originate from. This means that at least 8583 route/route6 objects refer to ASes not recorded in the IRR.

Someone creating route but not aut-num or creating route for someone else.

4911 AS Sets contain unrecorded `aut-num`s. ```rust >> query .as_sets .par_values() .filter(|as_set| !as_set.unrecorded_members.is_empty()) .count() 4911 ```

I'd like to have a look at some of the ASes that appear in route objects but do not have aut-nums. Are we somehow missing a registry? Maybe national registries like NIC.br?

@cunha, do you want to look at the ASes?

cunha commented 5 months ago

Yeah, I'd want to know that the ASNs are.

Here are the ASNs, @cunha.

cunha commented 5 months ago

So, it seems most of these ASes exist. Here is what some manual evalutation turns out:

16878,5  #ARIN **
53176,6  #NIC.br  no match
23640,8  #JPNIC **
62845,1  #ARIN **
267648,6  #REGISTRO.br
400672,3  #ARIN **
54112,8  #ARIN **
271217,4  #REGISTRO.br visible
266141,38  #REGISTRO.br
