It you use an new namespace within > existing DNS (ie a new top level domain) can't you achieve the > same effect? Several reasons: 1. Existing DNS servers are already loaded trying to deal with the existing namespace. A new port would seperate the load so that if the existing DNS space becomes to loaded in the future it does not affect the URN namespace and vice versa. 2. DNS server trees often do not correspond very well to the trees needed for information hierarchies. A seperate port would allow the two DNS trees to coexist but not comingle. 3. DNS servers are optimized for an extremely flat namespace (look at all the .com domains with no subdomains). A new namespace could potentially have a much different organization and hence caching requirments. 4. In order for URNs to be 'public'. I.E. we allow anyone to publish, not just those that have an in with the system admins; we need the URN resolution process to be able to take place on non privilidged ports. 5. It gives us a much much easier upgrade path in the future without affecting existing systems. -MM -- ------------------------------------------------------------------------------ Life is a game.
