Part of the conceptual problem is that Ethernet has evolved far from its coax origin, when it really was a broadcast medium. As soon as twisted-pair was born, Ethernet became *electrically* point-to-point, but continues to be logically broadcast. With fancy GBICs these days running GigE over dark fiber up to 70 km, Ethernet makes an awfully nice point-to-point technology. Despite all that, I've never seen a fixed point-to-point circuit that was not a /30 if it landed on its own interface at the ISP's router. The exceptions are all multiplexed/channeled at the ISP. I'm not sure RFC3021 is out there in the real Internet yet. Has anyone seen a T1 or better provisioned as a /31?
