E.g. it would be really wonderful if we had some way of finding out what range(s) of addresses belonged to XYZ Corporation, so that the configuration of the firewall of their commercial partner, ABC Corporation, could contain a single entry for "XYZ Corp's addresses", rather than list the actual addresses. As long as we are configuring things with actual addresses, it will remain incredibly painful to change them. Even worse, we're going in the *other* direction, and instead of adding another level of indirection, to provide new functionality, we're loading additional functionality (PI) onto the same old level of naming we already have. Architecturally-speaking, this design gets an 'F'. Noel _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
