as far as I can tell, for the most part, ISPs follow the constraints in the protocol specifications. frankly I don't see any way of having globally unique addresses that are inherently unroutable. and I don't know why ISPs are inherently less trustworthy than other parties. and I don't know why an ISP would accept advertisements for GUPIs from its peers unless it was paid (well) to do so. about all we can do is define the protocols. it's very difficult to build mechanisms that force people to adhere to those definitions. -------------------------------------------------------------------- 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] --------------------------------------------------------------------
