Overview

DNS C
OMMANDS
A Domain Name Server (DNS) Server provides an IP address for a host computer in
a given Domain.
A DNS Proxy receives requests and attempts to find an entry in its local tables, and
if one is not found, forwards the request to a remote server. The remote DNS
Server can be learned dynamically through PPP or via a DHCP client, or can be
statically assigned.
The DNS Proxy feature or the OfficeConnect Gateway enables you to configure
remote DNS Servers for specific Domains. For instance, assume you have two
remote sites configured, one to the Internet and the other to a corporate site
which has a domain name of 3com.com. Two DNS remote servers can be
configured, one which uses the corporate site for 3com.com and the other to use
the Internet as the default.
The DNS Proxy feature of the OfficeConnect Gateway also enables you to
configure Static Host entries. The static table is checked first before the DNS
request is forwarded on to the remote server.
This chapter identifies and describes the DNS commands accessible from the
OfficeConnect Gateway CLI. The following table identifies these DNS commands:
