I forgot how to do an inverse search to find my ASN in as-sets. So Google AI tells me: Yet: hank@nocvm:~$ whois -h whois.ripe.net -i members as378 % This is the RIPE Database query service. % The objects are in RPSL format. % % The RIPE Database is subject to Terms and Conditions. % See https://docs.db.ripe.net/terms-conditions.html % Note: this output has been filtered. % To receive output for a database update, use the "-B" flag. %ERROR:105: attribute is not searchable % % "members" is not an inverse searchable attribute. %ERROR:101: no entries found % % No entries found in source RIPE. % This query was served by the RIPE Database Query Service version 1.120 (DEXTER) What am I doing wrong?

Hi Hank, I think the syntax you are looking for would be something like this: whois -h whois.ripe.net -T as-set -i members AS378 But it's not actually supported by the RIPE DB (AFAIK).

Hi Hank, This isn't supported in the ripedb with inverse lookup, but you can check it out on IRR Explorer: https://irrexplorer.nlnog.net/asn/AS378 Nick Hank Nussbacher wrote on 17/12/2025 08:37:

As others have replied, the "members:" attribute is not (currently) inverse searchable. Only attributes marked as "[inverse key]" in the object template (using the "-t <object-type>" flag). Or listed in the DB documentation: https://docs.db.ripe.net/Types-of-Queries/Inverse-Queries https://docs.db.ripe.net/Tables-of-Query-Types-Supported-by-the-RIPE-Databas...
