Europe -- IPv6 is commonly supported by ISPs. Asia -- widely supported, some IPv6-only nets North America & Australia -- little support among ISPs USA NASA has some deployment. DOD began 2003, end Internet2 operated on IPv6. Many universities Operative System Support -- Windows 2000/2003 server/XP -- Linux (since 2.1.8) -- freeBSD, OpenBSD, NetBSD -- AIX 4.3, HP/UX 11.i, Solaris 8 & after, OSX
