RFC 1918 has caused a disaster in most networks that want e2e out of the site because NAT is required. 1918 was a band-aid because of shortage of IPv4 address space and because we did not get IPv6 done quick enough. I want SLs removed precisely because of what I have seen from 1918. I am speaking of the user of private addresses not CIDR. That was a good idea but actually illegal with IPv4 IMHO. /jim > > My $0.02 > > Michel. > > > -------------------------------------------------------------------- > 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] > -------------------------------------------------------------------- > -------------------------------------------------------------------- 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] --------------------------------------------------------------------
