ASN in use, but no whois data?

Hey folks,
I’m looking at an ASN 394183 and I can’t find any whois or other contact data. I’ve checked globally and then also ARIN directly and literally nothing as if it weren’t registered. It’s announcing prefixes, at least one of which is IRR invalid part of a larger old PSINET block, though, and I’m seeing them in the global routing table.

Anyone have any idea how this could happen where an ASN is in use, transiting several major providers to the internet, but no whois data as if it didn’t exist?

The AS customer could’ve churned from ARIN, freeing the ASN but leaving technically valid IRRs in databases such as RADb (which seems to be where they originate):

…thus allowing them to continue to announce their routes under that ASN as usual, even though technically it doesn’t exist in the ARIN WHOIS.


It appears like it might be but not clear to me
what happened with the contact data.

First stop for info:!

But yes, as others commented, looks like a ARIN-expired ASN... as long as one pay the bills at upstreams your data is safe :wink:


Yeah, in the wake of our peering survey, we’ve been looking into this… A surprising number of ASNs responded to the survey, but then we ran into errors when we went to geo-code their response to a country using the whois. There are zombie ASes like this in ARIN and in the IANA not-yet-delegated pool, but not in the other four RIRs.
