What is the "IPv6 Fix" activity?
As IPv6 is being deployed, many troubles appear.
Here are typical problems that we experienced.
- One day a person stayed in a hotel and plugged an Ether cable to
the information socket in his room. But Windows could not
gain access to any web pages. He asked the hotel and the hotel staff
told him,
type ipv6 uninstall
. After this operation,
the Windows came to be on the net.
(This is probably because of a poor implemented hotel system.)
- Mozilla on Linux 2.4 takes a few seconds to gain access to
web page which is provided with IPv4
but registered with IPv6 as well as IPv4.
(This is due to a harmful specification called "on-link assumption".)
- When an ISP installed BIND 9 to customer's network,
web browsers of the customer became slow to gain access to web pages.
(This is because BIND 9 can try to resolve names with IPv6 first
even if it does not have IPv6 connectivity, in which case the server will
endure hopeless timeouts.)
The causes of these problems include
harmful specification, poor implementations, and
poor-managed networks.
These flaws are minor, though,
they are enough to give a bad impression of IPv6 to end users.
The purpose of the "IPv6 Fix" program is to solve such problems
as soon as possible.
This program is operated by the WIDE project.
