Hi Denis, I support the idea of having empty AS-SETs deleted automatically and keeping only AS-NULL in the DB. @Edward Shryane question to the DB team: would it be possible to have some functionality in the LIR portal that converts the short-named AS-SETs to the hierarchical ones with a click of a button? That would help people transition much easier and faster to the hierarchical AS-SETs. Perhaps a button that can be triggered by user and 1) creates a new hierarchical AS-SET 2) copies all elements from old AS-SET to the new one 3) Deletes the old AS-SET 4) Updates the corresponding import/export rules.

One empty set is the same as any other empty set. We only need one clearly defined and easily recognisable empty set and we have that, AS-NULL. If I create an empty set, AS-WALKER it doesn't do anything that AS-NULL can't do. But AS-WALKER isn't instantly recognisable as an empty set. You have to query it to see that. If we have 100 empty sets in the database, including AS-NULL, that are all being used for valid reasons, 99 of them are redundant, duplicated objects and should be deleted...unless someone can tell me the value of a duplicated empty set. cheers denis co-chair DB-WG > > I can well imagine that most "operationally empty objects" > (as Denis put it) are either useless or troublesome. > > As Nick says, "Careful with this." > > Niall > > -- > > To unsubscribe from this mailing list, get a password reminder, or change your subscription options, please visit: https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ripe... -- To unsubscribe from this mailing list, get a password reminder, or change your subscription options, please visit: https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ripe...
