Transpector XPR 3+ Operating Manual
2.2.2 Subnetworking
A subnetwork (or subnet) is a logically visible subdivision of an IP (Internet
Protocol) network. Splitting an IP network into multiple subnets is referred to as
subnetting. Subnetting sets the region of the IP address that will be used as a
Network Prefix for all IP addresses inside of a subnet. This is accomplished
through a subnet mask. Different types of subnet masks and their implications to
IP addresses are shown in Table 2-1.
As seen in Table 2-1, the subnet masks determine which octets of the IP address
are used as the network prefix.
In order for two network devices to communicate, they must be on the same
subnet. This means that they must not only be connected to the same internet
network, but must also have the same network prefix. If two devices have two
different network prefixes, this means that the two devices are on different subnets.
2.3 Transpector XPR 3+ IP Address
By default, Transpector XPR 3+ ships with an IP address of 192.168.1.100 with a
subnet mask of 255.255.0.0.
NOTE: When connecting Transpector XPR 3+ to an existing local network, there
must be a static IP address for each Transpector XPR 3+ being installed.
Contact the network administrator for IP address assignments.
2.3.1 Changing Transpector XPR 3+ IP Address
There are two different methods of changing the Transpector XPR 3+ IP address.
The first method utilizes the onboard Transpector Web UI to change the
IP address. Instructions for changing the IP address via Transpector Web UI can
be found in section 2.3.1.1.1 on page 2-5.
Alternatively, the IP address can be changed through a standalone executable as
discussed next in section 2.3.1.1 on page 2-4.
