leaking the IX prefix to customers, to me, seems like a recipe for much wider/unintended leakage :(
Oh, it is. I remember when MAE-EAST was injected by at least 50 people into the DFZ because back then people weren't careful enough to just send such things to customers.
AMS-IX (and others) have the better solution. They have AS1200, announce the exchange LAN from AS1200 (195.69.144.0/22). They will peer with you if you are at the exchange, see http://www.ams-ix.net/as1200-peering/. I believe, but can't find a reference really quick that they get transit for it from a couple of providers so those that don't peer still have the route.
We advertise 195.69.144.0/22 with no-export. Kind regards, Martin
