Dear operations people! As you should know, the Internet is suffering from routing table explosion and it is only a questin of time until major routers which need a full routing table run out of resources. It is necessary to start aggregation *now*! Based on the current full routing table we compute the possible gain if aggregation is done at the AS level. This computation assumes that no holes will be created, i.e. aggregates do not include currently unannounced networks. All ASes should be able to achieve almost all the savings assumed by this computation. Please go ahead, start aggregating and remove the more specific announcements. This is a question of avoiding a big bang which will be desastrous to the Internet (industry). Think globally, act locally! These statistics and others are computed daily and can be retrieved from directory ftp.ripe.net:cidr/stats as long as the Internet continues to work.
