Before Installing the Software
To install the software over a network connection, a Ethernet cable and the supplied CD-ROM
are required. To automatically obtain the IP address, a router with a built-in DHCP server is re-
quired.

What is an IP Address?
The IP address is an identification number allocated to computers and other devices connected
to an IP network. An IP address is an address for use on a network. There are two types of IP
address: IPv4 and IPv6.
IPv4 address
The IPv4 address consists of four fields, such as "192.168.0.113". The first three fields
(192.168.0) are fixed, and the last one (113) is variable.

IPv6 address
Because IPv4 addresses are running out as a result of the widespread use of the Internet, IPv6
has been developed as a next generation Internet protocol.
