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
Unable to print using an IPv6 address
Symptom Remedy
When 0 (zero) is prepended to
the head of a value for the IPv4
address (for example:
192.0.2.010), connection fails.
Do not prepend 0 (zero) to each value of an IPv4 address.
Symptom Remedy
You cannot connect to the
machine with the link-local
address.
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 7 on Windows
Vista to access the address "fe80::203:baff:fe48:9010", you must
append the Ethernet adapter local area connection number (for
example, 8) for Windows Vista to the address as follows:
fe80::203:baff:fe48:9010%8
The machine cannot connect
to a computer running
Windows OS that supports
IPv6.
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.
A device outside the router
cannot be searched.
When searching for a device outside the router via SMB, directly
specify the address. Multicasting is supported only within a local
link (FF02::1).
When SSL is enabled on Dell
Printer Configuration Web
Tool, even if you specify "http://
[IPv6 address]", you are not
redirected to "https://[IPv6
address]".
When SSL is enabled, directly specify "https://[IPv6 address]".
Symptom Remedy
On an IPv6 network without a
DNS server, a computer
running Windows OS that
supports IPv6 cannot be
connected to a Windows
shared printer.
Register the computer name of the machine on the "hosts" file
stored on the computer running Windows OS that supports
IPv6. For example, register in the following file:
C:\Windows\system32\driver\etc\hosts
IPv6 communication cannot be
established with NetWare.
NetWare does not support IPv6 communication. Use IPv4 for
NetWare.
