Depends if that carrier only provides 3G IPv6 service. It may provide fixed and 3G service out of the same block, where the assignment is done differently in the fixed and wireless parts. Also, it may provide IPv6 service to corporate users which use prefixes belonging to their fixed corporate network. It's true that it doesn't provide privacy in all cases, but it's not necessarily a trivial thing to find out if a host is a 3GPP host. /Karim -------------------------------------------------------------------- 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] --------------------------------------------------------------------
