Default Gateway
The Default Gateway specifies the IP address of the gateway host, if available on the network.
NOTE The Default Gateway setting will be grayed out when the Use DHCP Server checkbox is
enabled. The value shown is the gateway assigned by the DHCP server.
The gateway host is responsible for sending and receiving data between hosts on different
networks, routing data packets from a sensor on the local subnet to a sensor on another subnet.
For example, if an In-Sight 3400 sensor will need to communicate with a remote host on a
different subnet, enter the address of the gateway sensor in the Default Gateway field. However,
if the sensor will need to communicate only with sensors on the local subnet, do not enter an
address for the Default Gateway (leave the field all zeros).
DNS Server
The Domain Name Server (DNS) specifies the IP address of the host on the network providing
DNS resolution, if available.
NOTE
The DNS Server setting will be grayed out when the Use DHCP Server checkbox is
enabled. The value shown is the DNS Server assigned by the DHCP server.
A Domain name (e.g., yourdomain.com) is an alias for a network (e.g., 192.168.0.0). A DNS
Server maintains the data cross-referencing host to IP addresses. The DNS Server setting
determines which host is contacted (by IP address) by translating a given Host Name into its
corresponding IP address.
Host Name
The Host Name assigns a name, or “alias”, for the In-Sight 3400 sensor, as it will appear when
browsing the network.
Each In-Sight 3400 sensor has its host name set automatically the first time it boots. The format
is “is3400_xxxxxx”, where “xxxxxx” consists of the last 6 characters of the In-Sight 3400 sensor’s
unique MAC address. For example, an In-Sight 3400 sensor with the MAC Address 00-d0-24-14-
15-16 will be assigned the host name, “is3400_141516”.
NOTE
The Host Name setting is not automatically assigned by the DHCP server (if used) or
referenced through the DNS server. If the Use DHCP Server checkbox is enabled and
the DHCP server supplies the Host Name, it is ignored in favor of the default host name
or the name entered by the user.
Domain
The Domain specifies the In-Sight 3400 sensor’s Fully Qualified Domain Name (FQDN) for the
network on which it is installed.
NOTE
When the Use DHCP Server check box is enabled, this field is grayed out and displays
the value assigned by the DHCP server.
