We pull automatically from the standard URL, https://www.seattleix.net/participants/table but have to try to uniq it to not double-count organizations that are peering under multiple ASNs, who are peering on multiple subnets, etc.  Because we’re doing that 400 times per day, it’s all automated with rulesets and a whole lot of exceptions (knowing that AS 701, 702, 703 are the same organization, etc.).

Presumably we have some rules that are detecting that AS42 and AS3856, for instance, are the same organization and consolidating those.  I’ll have our IXPdir maintenance staff take a look at where the differences lie, and whether any of those rules need to be updated.

Is that a good idea?

For instance, if I were stupid enough to peer with as3856 and not with as42 (because not peering with either of those is idiotic :), would I get the same data as peering with both?

It is absolutely true that if I peer with as702, I do _not_ get the same prefixes as peering with as701. Just because one is a downstream of the other does not mean they are separate (from BGP's PoV).
