1 Currently, internet packets are routed without regard to what they’re carrying, and many “major” sites like barnesandnoble.com have just one internet address (208.237.178.21) just as artcontext.com has one (199.105.128.138). This situation is changing, however. The forthcoming IPV6 (“[Internet Protocol version 6] has a built in charge back mechanisms to bill for traffic”, Network World, March 1, 1999), Virtual Private Networks, Service Level Agreements (ensuring guaranteed service levels), and MPLS (Multi-protocol Label Switching, which will enable pay-services [eg. movie delivery] to get higher priority in routing of data over the internet), all combine to paint a very different looking future for what was potentially an unhierarchical network.
