As far as I can see, the safe way to do "two-faced" DNS with site locals is to make the site-scoped DNS itself be addressable only by a site-scoped address. Otherwise, you breach the principle that a site local address MUST NOT exist outside the site. >From this, it follows that the DNS is topologically located inside the site. -- Andrew White [EMAIL PROTECTED] -------------------------------------------------------------------- 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] --------------------------------------------------------------------
