in the DSL world, when we were providing service using Bridge PVC's, it was easier to allocate (as many needed) /32 to a customer CPE, than to route a subnet. This changed when the AT&T/BellSouth infrastructure changed from being able to get ATM PVC's to PPPoE only network.

And people wonder why Verizon is the first to whine about routing table growth from deaggregation? ;-)
eh, these end up (I think) aggregated on the edge router, so you get 5 /32's from a /23 (or the like) routed to the edge layer3 device. not as bloaty for the rest of their network as it at first seems.
In all seriousness, though, I don't think they are routed as /32s. I think that's one for the Verizon CPE, 5 for your devices all routed as a single /29.
owen, seen the config on a live router, yes they are routed as /32's to the VC you are connected to. I probably have the config for my old link in IM/email somewhere. apparently their automation either doesn't understand CIDR, or it was 'too expensive' to make the automation do CIDR once they started to offer extra ips to the business customers.
