Level Up to IPv6 with Ubuntu 10.10 on Comcast (Linux.com)

I took care of a ipv6 only computer class starting 2 and a half years ago. There was a www-proxy that could resolve both ipv4 and ipv6 addresses. Only cases where users did notice the missing ipv4 support was with remote ftp-servers. You need the correct protocol when you send new files to them. Reading files from ftp-servers can be easily done with web browser and a proxy.

Network disks, printers and most of the software has been usable with ipv6 for a long time. With software you still need to select versions that have ipv6 support. However each software type already has some versions that have ipv6 support.
