No you don't. You've never written a multiparty app that has to cope with the conditions you are trying to impose on apps. If you had, you wouldn't be dismissing the extra complexity required to do this as "some work" and you wouldn't be dismissing the problems as Chicken Little claims. For better or worse, the current TCP/IP architecture uses IP addresses as both attachment names and endpoint names. That might be unfortunate, but you can't fix this by dismissing the use of IP addresses as endpoint names as inappropriate, declaring that the network no longer has to provide a coherent, uniform view of addressing, and pretending that any lack of coherency in the network is now the apps' problem to solve. Moving the problem from layer 3 to layer 7 doesn't solve it; it makes it more difficult to solve. If you want to really fix this you need to create real endpoint names, provide a fast and reliable layer of indirection between these names and addresses, and change the transport protocols to allow them to use those endpoint names instead of addresses. Until those changes are made and deployed, it will continue to be perfectly reasonable for apps to pass IP addresses around, and it's the network's job to maintain a coherent view of addressing for hosts to use. Even when those changes are made, much of the responsibility for maintaining that mapping layer must still lie with the network. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
