Configuring environments without a DNS
The Domain Name System (DNS) is an Internet service that translates domain names into IP
addresses. Because domain names are alphabetic, they are easier for subscribers to remember. The
Internet is based on IP addresses. Every time you use a domain name, therefore, a DNS must
translate the name into the corresponding IP address. For example, the domain name
www.example.com can translate to 198.105.232.4.
If one DNS server does not know how to translate a particular domain name, it asks another one,
and so on, until the correct IP address is returned.
Desktop Messaging uses Domain Name resolution, which is provided by a DNS. If your network
does not have a DNS, then you must configure Desktop Messaging to use IP addresses.
Configuring Desktop Messaging with IP address only
If you do not use DNS to resolve domain names, configure CallPilot 100/150 and client computers
to use an IP address only:
1 Ensure your CallPilot 100/150 system is not configured to use DNS.
2 Enter the host name on CallPilot 100/150.
3 Configure computers running Desktop Messaging with the IP address of CallPilot 100/150.
