IPv6 Addresses
Restrictions
This section explains the restrictions on network connection using an IPv6 address.
CentreWare Internet Services
• When SSL is enabled, “http://[IPv6 address]” entered on a web browser is not
redirected to “https://[IPv6 address]”. Directly specify “https://[IPv6 address]”.
Printing
• The following operating systems support IPv6 printing.
– Windows Vista
– Mac OS except Mac OS X 10.4 and earlier
– Linux distributions with CUPS that supports IPv6
• The WINS protocol does not support IPv6 communication.
• On an IPv6 network without a DNS server, the machine cannot be connected to
Windows Vista via SMB.
• NetWare does not support IPv6 communication. Use IPv4 for NetWare.
• Bonjour does not support IPv6 communication. Use IPv4 for Bonjour.
Scanning
• When IPv6 is enabled and IPv4 is disabled on the machine, the Browse function of
the Scan to PC (SMB) service is not available.
• In an IPv6 network with no DNS server installed, the file transfer using the Scan to
PC service fails if a destination server is specified using the computer name. Directly
specify the IPv6 address.
Discovery
• IPv6 devices cannot be searched in UPnP. Use the WSD discovery function for IPv6
device search.
Authentication
• In an IPv6 network without a DNS server, SMB authentication fails if an SMB server
is specified using the computer name. Directly specify the IPv6 address.
Connection to External Applications (Custom Services)
• External applications, such as DocuShare, cannot be specified in IPv6 address
format. The machine supports only the domain name format or the IPv4 format to
access external applications. In IPv6 environment, use a DNS server and specify
applications in domain name format.
