I am connected through this one: Access-Concentrator: DARX41-erx AC-Ethernet-Address: 00:90:1a:a0:01:46 -------------------------------------------------- I guess dtag.de has got some 8 of them. Everybody (almost) offering dsl in germany goes through their infrastructure. The ip address range 84.167.0.0/16 seems to be shared by all of them.
But you've got an ATM PVC to them, haven't you? This is a completely different setup. Imagine you haven't got a DSL modem, but just an RJ45 plug in the wall which leads into a stupid cloud of L2 Ethernet switches, and you still talk PPPoE to your ISP. AFAICS, this is the kind of network setup the OP is talking about.
