IPv4 and IPv6 Connection Problems

The possible causes and remedies for problems when using an IPv4 or IPv6 address are as
follows:
Unable to connect using an IPv4 address
Unable to connect using an IPv6 address
15
534
Cause
The setting to use the proxy
server is not configured.
The setting to use a proxy server
is configured even though the
environment does not use a
proxy server.
The proxy server address is
incorrect.
When the proxy server access
requires authentication, you
cannot connect to the server
because the user name or
password is incorrect.
Symptom
When 0 (zero) is prepended to
the head of a value for the IPv4
address (for
example:192.0.2.010),
connection fails.
Symptom
You cannot connect to the
machine with the link-local
address.
The machine cannot connect to
a computer running Windows
OS that supports IPv6.
Remedy
In the environment using the proxy server, you must
configure the machine to use the proxy server to
connect to a desired Web server. Make sure that you
configure the settings to use the proxy server.
In an environment that does not use a proxy server,
such as when connecting to an intranet, do not make
the settings to use the proxy server.
When the settings to use a proxy server are configured,
you cannot connect to a desired Web server only if the
IP address of the proxy server is correct. Set the correct
IP address of the proxy server.
Set the user name and password on the machine that
allow connection to the proxy server.
Remedy
Do not prepend 0 (zero) to each value of an IPv4
address.
Remedy
When you specify the machine's link-local address, a
scope ID must be appended to the address. For
example, when you use Internet Explorer 11 on
Windows 7 to access the address
"fe80::203:baff:fe48:9010", you must append the
Ethernet adapter local area connection number (for
example, 8) for Windows 7 to the address as follows:
fe80::203:baff:fe48:9010%8
Assign a static IPv6 address to the computer running
Windows OS that supports IPv6. Then, register the IPv6
address on the machine as host address to allow
communication.
