Hi, I personally recommend the database documentation over asking a hallucination generator to come up with a human sounding text, especially for niche subjects. Yet, it is not entirely false, as you can do exactly this in IRRDv4, e.g. `-i members AS378` against rr.ntt.net <http://rr.ntt.net/>, or https://rr.ntt.net/v1/whois/?q=-i%20members%20AS378 (or another IRRD instance). Might be more practical if you want to automate.
Or, save yourself the RPSL parsing and use GraphQL on e.g. https://rr.ntt.net/graphql/: ``` query { rpslObjects(members: "AS378") { rpslPk source mntBy ... on RPSLAsSet { descr } } } ``` IRRexplorer runs roughly that GraphQL query in the background for the as-set membership table. Plus a check on `member-of` on the aut-num/as-set.
