Speakeasy has their customers configure their networks as a /24 even though particular customers normally only get 2 ip addresses. There is some filtering that goes on so that SE's equipment does the equivalent of proxy arp so that you don't see other customer's arp requests and your requests for other customers ip addresses will get the mac address of the gateway (or DSL modem) as a response.
