6.2 DNS Server
Domain Name System (DNS) provides a service that translates domain names
into IP addresses and vice versa. The DNS server of the GlobeSurfer 3G is
an auto-learning DNS, which means that when a new computer is connected
to the network the DNS server learns its name and automatically adds it to
the DNS table. Other network users may immediately communicate with this
computer using either its name or its IP address.
In addition, the DNS server:
• Shares a common database of domain names and IP addresses with the
DHCP server.
• Supports multiple subnets within the LAN simultaneously.
• Automatically appends a domain name to unqualified names.
• Allows new domain names to be added to the database using the GlobeSurfer
3G management console.
• Permits a computer to have multiple host names.
• Permits a host name to have multiple IPs (needed if a host has multiple
network cards).
The DNS server does not require configuration. However, you may wish to
view the list of computers known by the DNS, edit the host name or IP address
of a computer on the list, or manually add a new computer to the list.
6.2.1 Viewing and Modifying the DNS Table
• To view the list of computers stored in the DNS table:
1. Click DNS server on the Advanced screen of the management console.
The DNS table is displayed, showing the list of computers stored (see
figure 6.3).
