That's true, but when was the last time your mother entered an IPv4 address? DNS is the solution to this. Most mere mortals don't even know what an IPv4 address is, and they won't care if the IPv6 address is longer. Network techs may grumble, but the autoconfiguration of IPv6 should itself save them enough angst to make the whole deal a wash (if not an improvement).

There was actually a thread on the IETF discussion list awhile back in which a lot of use of IPv4 dotted quad addresses was given as examples of the pain of renumbering. One reason DNS isn't used in these cases is because connectivity to the resources at these addresses needs to work regardless of whether DNS is available. Another reason is because filtering must be done on the addresses because it takes too long to do DNS lookups.

BTW, ipv6.org doesn't resolve to v4 or v6 addresses, but www.ipv6.org does.

The OLPC laptops are actually using a very cutting-edge mesh network -- the first implementation of the new 802.11s specification.
