In-Sight 3400 Installation
Unlike the factory-set MAC address, the IP address is assigned automatically by a DHCP server
or can be manually assigned by the user (also referred to as a static IP address). The following
IP addressing schemes are recommended:
Table 2-2: IP Address Schemes
ADDRESSING
SCHEME
DESCRIPTION
10.0.0.0/8 The 10.0.0.0/8 private network is a class A network ID that
allows valid IP addresses from 10.0.0.1 to 10.255.255.254. The
10.0.0.0/8 private network has 24 host bits, which can be used
for any subnetting scheme within the private organization. The
default Subnet Mask is 255.0.0.0.
172.16.0.0/12 The 172.16.0.0/12 private network can be interpreted either as
a block of 16 class B network IDs or as a 20-bit assignable
address space (20 host bits) which can be used for any
subnetting scheme within the private organization. The
172.16.0.0/12 private network allows valid IP addresses from
172.16.0.1 to 172.31.255.254. The default Subnet Mask is
255.255.240.0.
192.168.0.0/16 The 192.168.0.0/16 private network can be interpreted either as
a block of 256 class C network IDs or as a 16-bit assignable
address space (16 host bits), which can be used for any
subnetting scheme within the private organization. The
192.168.0.0/16 private network allows valid IP addresses from
192.168.0.1 to 192.168.255.254. The default Subnet Mask is
255.255.0.0
Subnet Mask
The Subnet Mask defines which part of the In-Sight 3400 sensor’s IP address refers to the
network and which part refers to the host.
NOTE
When DHCP is enabled, this field is grayed out and displays the value assigned by the
DHCP server.
The network part of the IP address is the same for all hosts on the same subnet, and the
remainder is unique to each host. As shown in Table 2-3, a Subnet Mask of 255.255.255.0 (a
class C mask) identifies 24 bits for the network portion and 8 bits for the host portion.
Table 2-3: Subnet Mask Formats
MASK CLASS DESCRIPTION
255.0.0.0 A 8 network/24 host
255.255.0.0 B 16 network/16 host
255.255.255.0 C 24 network/8 host
Most users will not need to change the default Subnet Mask setting of 255.255.255.0.
