Static IP Address

A static IP address is a fixed IP address that the user assigns manually to the CXC or to a PC

or any other device on the network. This address remains valid until the user disables it, thus

ensuring that the device will always have that same IP address until the user changes it. Check

with the LAN administrator to see if they have allocated a Static or Dynamic IP address for the

CXC on the network.

Dynamic IP Address

A dynamic IP address is one that is automatically assigned to any device on the LAN network.

This address is called “dynamic” because it is only temporarily assigned to the CXC, PC or

other network device. After a certain time, it expires and may change. If a PC logs onto the

network (or the Internet) and its dynamic IP address has expired, the DHCP server (see below)

will assign it a new dynamic IP address.

NOTE: DHCP Server (8.1.1.5) may choose to assign the same IP address every time

based on the MAC address.

Subnet Mask

The Subnet Mask (also known as the Network Mask) determines which portion of an IP address

is the network portion, which portion is the host portion, and directs the CXC regarding

communications via the Default Gateway (8.1.1.4).

If not connected to CXC via crossover, hub, or switch, then misconfigured subnet and gateway

will result in the inability to communicate with the CXC.

Default Gateway

This IP address should be the IP address of the gateway device that enables contact between

the CXC and the remote network or host. If the destination node is not in the local sub network,

the protocol is sent to the default gateway (and may not be required for a small network).

DHCP (Dynamic Host Configuration Protocol) Servers

A DHCP server can automatically assign a new IP address to the CXC (or any other network

device that uses dynamic IP addressing). In this case, the CXC is called the DHCP client.

DHCP frees the administrator from having to assign an IP address manually every time a new

user is added to the network. A DHCP server is usually a dedicated network device such as a

router or firewall.

By default, the CXC is configured to enable the DHCP client (the “Obtain Address

Automatically” checkbox is selected). If the DHCP Client is enabled, then the DHCP server

automatically provides the Subnet Mask and Default Gateway parameters. If the DHCP client is

disabled (clear checkbox for “Obtain Address Automatically”) then it is possible to explicitly

specify the Subnet Mask and Default Gateway.
