For optimum routing, and neutrality, at least in the case of the RIPE NCC (and maybe some of the IXes service networks), you want all upstreams (90) to reach their network directly, not going over other peers. So you either take 90 /48s, or take one, and announce that to all the peers/ upstreams (which is mostly the same in these situations).
Note that we are not talking about 90 /48s here, but 90 /64s, one from each of the peers. So, you connect your DNS server with an 802.1Q compliant NIC, two-thirds of these 90 VLANS already exist in the exchange's L2 fabric.
These VLANs do not already exist (at least not at AMS-IX). Every IXP member peers within the same VLAN. Their interfaces connected to this VLAN are configured with an unique address out of the same /64. This is how I understand your proposed setup: - Connect this DNS server directly to the L2 IXP infrastructure via an 802.1q NIC. - Configure n VLANs on it - one for each peer. - In each VLAN, the server answers DNS queries on a different /64 address. - Each of these /64 belongs to the aggregate of the respective peers. Is this an accurate description?
Where is your problem?
Well, *if* my understanding is correct. Then I do see a number of issues. Arien -- Arien Vijn Amsterdam Internet Exchange http://www.ams-ix.net
