If DNS is not available you must do one of the following:
• If your digital network contains sites with sites other than Business Communications Manager
and CallPilot 100/150, you must use a hosts file to provide consistent name mapping
throughout the VPIM network. If you use CallPilot 100/150, refer to
“Creating and installing
hosts files on CallPilot 100/150” on page 21 .
• If your digital network contains, and will only contain, Business Communications Manager or
CallPilot 100/150 sites, you can use IP addresses to create network sites. Refer to
“Configuring Business Communications Manager to use IP addresses” on page 16 or
“Configuring CallPilot 100/150 to use domain names or IP addresses” on page 19 to create
network sites using IP addresses.
Configuring Business Communications Manager to use IP
addresses
1 Ensure no DNS servers are currently configured. Refer to “Ensuring no DNS servers are
configured on your Business Communications Manager” on page 17 .
2 Enter the hosts name on the Business Communications Manager system. Refer to “Entering a
Host Name on the Business Communications Manager system” on page 18 .
3 Configure computers running Message Networking with the IP address of the Business
Communications Manager system.
Note:
You can use a hosts file in combination with DNS in situations where DNS
is not available in all branch locations.
Note: The DNS servers must provide constant name mapping throughout the network.
Host files can be used to augment DNS if necessary. An instance where both hosts files
and DNS may be required is when a Business Communications Manager is used as a
gateway between a private network and an ISP.
