Windows 2003 of course also includes IPv6 support out of the
box. But it still isn't switched on by default. Next to the command
line option to install IPv6, this version of Windows also includes
the option to install the IPv6 protocol through the graphical user
interface.
IPv6 is installed by opening the network properties of the current
LAN connection. The tab "General" includes the functionality to
install additional network protocols. Just click on "Install" and
search for "Microsoft TCP/IP Version 6" in the list of protocols.
Select it and click "Ok". IPv6 is now installed and enabled.
Uninstallation of IPv6 works just like with any other network
protocol. Just select it in the list of installed protocols and click
"Uninstall".

Windows 2003 Server - 2
all configuration options for IPv6 have been
included into the normal netsh command. All
interface specific IPv6 options as well as ISATAP
and 6to4 configuration settings are accessed
through :
-
c:\ netsh interface ipv6 ?
-
File/print sharing-et (site-local) supported over IPv6
-
IIS and media server also support IPv6

Bind is available on the following url
http://www.isc.org/prodcts/BIND/
The configuration files of bind are :
/etc/named.conf
/var/named/zonefiles

The default behaviour of bind is that it listens by
default on IPv4 requests only. To have bind listen
to IPv6 requests as well, the following
configuration statements must be added in
named.conf:
options {
listen-on {any; };
listen-onv6 {any; };
};

IPv6 Host Configuration
IPv6 DNS
More in depth:
The IPv6 DNS resolution is independent from the protocol used for
transport of DNS requests. For example it is possible to use IPv4 to
request AAAA records.
The hosts choose a server based on the DNS address server given in
the /etc/resolv.conf file. If the address of the name server in the
/etc/resolv.conf is an Ipv6 one, then the hosts will make only IPv6
DNS requests.
For PCs under Windows (2000 and XP), it is not possible to use Ipv6
for DNS transport.
IPv6 Host Configuration
IPv6 DNS
Test the DNS server using:
nslookup -type=AAAA hostname
ping6 –H addressv6
traceroute6 addressv6
hosts –t or dig
IPv6 Host Configuration
IPv6/v4 Dual Stack web server
The server configuration has no diference with the classical set up
of an IPv4 server. The main configuration file is in the directory
/etc/httpd/conf/httpd.conf
The admin also has to specify the addresses and ports on which
ther serverlistens, for example:
Listen 203.141.43.130:80
Listen [2001:e30::DEAD:BEEF]:80
Listen 80
Many other parameters can be added to configure the dual stack
web server. The server can then be configured without taking into
account the IP protocol version.
IPv6 Host Configuration
IPv6/v4 Dual Stack web server
To test the web server installed, we can use any IPv6
enabled web client. There are many browsers already
availble with an Ipv6 support. Mozilla, Opera or
Konqueror can be used for example on computers with
UNIX. For windows, IE now fully supports IPv6.
The IPv6 support in Mozilla is automatic. To be sure that
Ipv6 is used for communication with a dual stack web
server, it is possible to add the IPv6 addres in url using
the textual format with the brackets.
Eg. http://[2001:e30::DEAD:BEEF]
IPv6 Host Configuration
IPv6 Mail
Most used SMTP servers support IPv6. Sendmail
(http://www.sendmail.org) that supports IPv6 since
release 8.10, Exim (http://www.exim.org ) from release
4.10 and Postfix (http://www.postfix.org ) can be patched
to support IPv6.
Over the years, Sendmail has matured to the point that
every feature available with IPv4 can now also be used
with IPv6, for example, transfer to and from an IPv6enabled host or server, filtering, and redirection.
We have used sendmail-8.12.11-4.6 for this Task.
IPv6 Host Configuration
IPv6 Mail
Edit your sendmail.cf located in /etc/mail directory
Uncomment The following lines with the appropriate
IPv6 interface address just below the section SMTP
daemon options
DAEMON_OPTIONS(`Name=MTA-v4, Family=inet,
Name=MTA-v6, Family=inet6')dnl
Run “make –C /etc/mail” command to compile
sendmail.mc file.
Restart or HUP sendmail and watch for errors
Test your smtp server using telnet ::1 25
IPv6 Host Configuration
IPv6 POP3 & IMAP
IPv6 IMAP an POP have been supported by many
MTA’s eg. UW Imap, Courier Imap, Cyrus Imap,
Dovecot, Popper etc.
For our testings we have used Dovecot IMAP
Server.
Simply edit /etc/dovecot.conf file and add these
two lines
imap_listen = [::]
pop3_listen = [::]
IPv6 Host Configuration
IPv6 POP3 & IMAP
Simply restart the dovecot demon and test your
IPv6 IMAP or POP3 server by using and IPv6
compliant MUA.
There are still few IPv6 enabled SMTP, POP3 and
IMAP clients. Sylpheed is a client with a
graphical interface under Unix & windows that
supports all these features since release 0.4.4.
More info about this software can be found at

IPv6 NTP
Some Ipv6 NTP servers already exist. NTP is
very important as time is required for most
management functions (logs, one way delay
calculation….).
There is an list of IPv6 NTP servers available at:

An IPv6 release of ntpdate can be found at the
