USR-DR13X User Manual
3.1.2. IP settings
You must assign a valid IP address to the USR-DR13X before it will work in your network environment. The
IP address must be unique within the network. If the device is connected to the Internet and should connect to
other servers over the Internet to get some services such as Network Time Protocol (NTP) server, you will need
to configure the DNS server to be able to resolve the host name of the NTP server. The detailed description of
the configuration parameters on this interface is shown in Table 7.

IP address is a 32-bit address assigned to devices connected to the Internet. The IP
address consists of two fields: the network number field (Net-id) and host number field
(host-id). In order to facilitate the management of IP addresses, IP addresses are
divided into five categories: Class A, B, and C addresses are unicast addresses, Class D
addresses are multicast addresses, Class E addresses are reserved addresses for future
special purposes. The IP addresses currently in large numbers belong to three types of
addresses: A, B, and C.
