Domain name The network name to which the network-connected PC belongs.
Host Name Name of PC (or VR-509) on the network.
The name of the PC connected to the network is managed by a database called DNS (Domain
Name System). DNS links the IP address assigned to each PC with the domain names, and
enables a user to specify a PC to access.
IP Address An identification number assigned to ea ch PC connected to the network. This is used for
communication between network devices.
There are 2 types of IP address, namely Global IP Address and Local IP Address (Private IP
Address).
IP Address Host Name Domain Name
Convert
IP addresses assigned by the PC are converted by the DNS server into host names and domain
names.
Global IP Address Just as separate IP addresses are required on a network, this is also required for all PCs that are
connected to the Internet throughout the world. These IP addresses are known as Global IP
Addresses, and are usually assigned by the Internet service provider.
Local IP Address Separate IP addresses can be used freely within networks that are not connected to the Internet
(eg. within a family or company). These are known as Local IP Addresses.
DHCP (Dynamic Host
Control Protocol)
This is a method that automatically assigns IP addresses on the network.
The DHCP server will automatically assign an IP address to a PC when it is connected to the
network.
Subnet mask A mechanism that manages a netw ork by segmenting it into multiple virtual networks (subnets).
Subnet mask is a 32-bit value that is used to define how many bits are to be used within the IP
address for identifying the subnet.
LAN
(Local Area Network)
A network that is built within a comparatively confined area such as within a building, company or
office.
Default Gateway Hardware and software that are used mutually for the translation of different protocols during
communication of a PC with one that does not belong to the same network. In Windows, setting
of a default gateway is required when setting the IP address.
Protocol A set of rules used for communication of PCs or devices via the network.
TCP/IP Abbreviation for Transmission Control Protocol/Internet Protocol. This is one of the protocols
used by the network.
Login Refers to the commencement of use upon connection of a PC terminal to an online database or
server.
Peer-to-Peer A small-scale network that connects PCs on a peer level (1-to-1).
NTP A system that automatically synchronizes the system clocks of equipment connected to the
network.
The NTP Server function is built into WindowsXP, Windows 2000 as a standard feature. (Page 107)
The NTP server can also be accessed and used via the Internet.
