DHCP server
DHCP (Dynamic Host Configuration Protocol) is a
protocol that allows a client in a TCP/IP network to
automatically obtain required information from a
server. 
The DHCP server manages such network infor-
mation as the IP Address, Default Gateway, and
Domain Name.
The AP-3 is provided with a DHCP server that allo-
cates an IP address, default gateway, DNS
address, etc., to the DHCP clients (computers)
when the DHCP clients start up.
DNS (Domain Name System)
DNS is a name resolution service for TCP/IP net-
works.
The AP-3 provides a domain name service, in
accordance with DNS, that allows computer
names and domain names to be registered in a
domain name server. 
By using the domain name service, the IP address
of the desired site can be designated not as num-
bers but as easy-to-understand domain names
and host names.
ESS ID
An ESS ID is a name used for identification when
multiple network groups are formed within the
transmission area of a wireless network. The ESS
IDs of the wireless terminals in a wireless network
group communicating with the AP-3 are set to the
same value as the ESS ID of the AP-3.
ETHERNET
Ethernet is a set of standards and protocols for
LAN communications developed by Xerox, Digital
Equipment Corporation, and Intel. Types of
Ethernet include 10BASE-T, 10BASE-5, and
10BASE-2, each requiring a different cable speci-
fication.
IP (Internet Protocol) address
The IP address is a 32-bit address used to distin-
guish the devices in a network constructed using
TCP/IP protocol. Each network device has a
unique IP address.
The IP address is usually expressed as a base-10
numeral string made up of four 8-bit sections
(Example: 192.168.0.1). 
A private IP address is an IP address set indepen-
dently by the network manager. It is not necessary
to petition an address management institution or a
provider, but a private IP address must be allocat-
ed according to the following rule: When connect-
ing with an external network, the private address
must be converted into a global IP address.
The following IP addresses can be used freely as
private IP adresses:
Class A: 10.0.0.0 to 10.255.255.255
Class B: 172.16.0.0 to 172.31.255.255
Class C: 192.168.0.0 to 192.168.255.255
LAN (Local Area Network)
A network that is relatively small in scale. A typical
LAN occupies a single office or a single floor of a
building.
MAC address (Media Access Control Address)
A MAC address is a physical address (number)
uniquely set into each wired or wireless LAN card.
LAN card manufacturers manage MAC addresses
so that no two LAN cards in the world have the
same MAC address. Ethernet uses the MAC
address to send and receive frames.
RIP (Routing Information Protocol)
RIP is a protocol used in a TCP/IP network to
exchange routing information between routers.
Routers use RIP to send packets to the correct
destination.
SYSLOG
SYSLOG is a function for sending system mes-
sages to destinations within a network.
Log information can be managed using a UNIX or
other SYSLOG server if the network supports this
function.
TCP/IP
TCP/IP is the basic protocol of the internet and is
currently the most popular protocol in the world. It
is supported by Windows 95/98, Windows NT, and
the other major operating systems.
SMTP and FTP use this protocol.
A TCP/IP control panel is a standard item in
Macintosh computers provided with Open
Transport.

sites on the internet.
Our URL is http://www.icom.co.jp.
