About Using IPv6 Addresses in ConferenceXP
ConferenceXP 3.2, Venue Service 2.1 Reflector Service 1.2, and Archive
Service 1.1 support the IPv6 protocol, which enables you to use IPv6 unicast or
multicast addresses. To use IPv6 addresses, you’ll need to install the IPv6
protocol on Windows XP or Windows 2003. Then you can join a IPv6 venue in
ConferenceXP Client 3.2, create IPv6 venues in Venue Service 2.1, and enable
IPv4 clients to join IPv6 venues in Reflector Service 1.2.

Installing the IPv6 protocol
You can install the IPv6 protocol stack by using the Network Connections folder or by using the command prompt, depending on which version of Windows you’re using. After you install the IPv6 protocol, you can view your IPv6 configuration.
Install the IPv6 protocol
View your IPv6 configuration
- Click Start, point to All Programs, point to
Accessories, and then click Command Prompt.
- At the command prompt, type:
ipconfig
Looking at the network configuration for your network
adapter (not the tunneling interfaces), you will see several IP addresses, one
in IPv4 format and the others in IPv6 format, which include hexadecimal digits. The first four digits of an IPv6
address determine the type of the IPv6 address:
-
If the first digit is a 2 or 3 (for example,
3000::1:206:5bff:febd:c563), it is a Aggregatable Global
Unicast address, which is like an IPv4 address that is routable throughout the
Internet.
- If the first two digits are FE and the third digit is 8, 9, A or
B, it is a Link-Local address. This address doesn’t travel beyond any router,
and it is mainly used for neighbor discovery.
- If the first two digits are FE and the third digit is C, D, E or
F, it is a Site-Local address. These addresses don’t travel beyond organization
edge routers, similar to IPv4 private IP addresses (for example, 192.168.x.x or
172.16.x.x).
By default your computer is assigned only a Link-Local
address. If you get a Site-Local or Global address, that address is published by
your router or gateway. If the router is properly configured, the addresses in
the configuration represents the scope of your IPv6 connectivity.
In the default configuration, you will have two addresses
from each type (if you have any). One of the addresses always has a constant
postfix, and the other address will have a random postfix. This is meant to be
used for anonymity, but causes different problems in the case of IPv6 multicast.
To turn off this feature in Windows XP, at the command prompt, type ipv6 -p gpu
UseTemporaryAddresses no, and then restart your computer.
If you don’t have a Global or a Site-Local IPv6 address,
consider setting up a test lab to do so. For instructions, see
Setting up an IPv6 test lab.
Setting up an IPv6 venue
With ConferenceXP Venue Service
2.1, you
can create IPv6 multicast venues by simply specifying an IPv6 multicast address (e.g., ff1e::900) instead of
an IPv4 multicast address. You can also create a custom venue from the command line.
View the IP address of a venue
- In the ConferenceXP window, pause your mouse over the venue you want.
Define a custom venue from the command line
- In Windows XP, click Start, point to All Programs, point to
Accessories, and then click Command Prompt.
- At the command prompt, change the directory to the ConferenceXP
installation directory (by default, C:\Program Files\Microsoft
Research\ConferenceXP\CXPClient).
- At the command prompt, type: CXPClient.exe –IP IP1 –Port P1
where IP1 is either a multicast or unicast IPv6 or IPv4 address and
P1 is the port
number
For example, CXPClient.exe –IP 3000::1:bc3b:f021:3e1a:9ff1 –Port 5004
uses a unicast address and CXPClient.exe –IP ff1e::9000 –Port 5004 uses a
multicast address.
For more information about specifying IPv6 multicast addresses, see
Internet Protocol Version 6 Multicast Addresses.
For more information about protocol compliancy, see
RFC2464.
For more information about starting ConferenceXP from the
Command Prompt window, see
ConferenceXP Command Line Parameters.
Using the IPv6 Reflector Service
ConferenceXP Reflector Service 1.2 also supports the IPv6 protocol. You can
use the Reflector Service 1.2 to connect to
an IPv6 or IPv4 multicast venue by specifying the IPv6 address of the reflector (e.g.,
3000::1:212:79ff:fed2:f77)
in the ConferenceXP Services dialog box, and then joining the IPv6 or IPv4
multicast venue you want.
You can configure Reflector Service 1.2 to support IPv4, IPv6,
or both by editing the configuration file. If you want the
reflector to be IPv6 enabled, you must
install and configure the IPv6 protocol. If the Reflector Service 1.2 computer is getting the IPv6 address automatically,
it’s enough to have the reflector working properly.
