NAT
Network Address Translation. A network algorithm used by Routers to enables several PCs to share
single IP address provided by the ISP. The IP that a router gets from the ISP side is called Real IP,
the IP assigned to PC under the NAT environment is called Private IP.
DHCP
Dynamic Host Configuration Protocol. A protocol that enables a server to dynamically assign IP
addresses. When DHCP is used, whenever a computer logs onto the network, it automatically gets an
IP address assigned to it by DHCP server. A DHCP server can either be a designated PC on the
network or another network device, such as router.
DNS
A program that translates URLs to IP addresses by accessing a database maintained on a collection or
Internet servers.
DDNS
Dynamic Domain Name System. An Algorithm that allows the use of dynamic IP address for hosting
Internet Server. DDNS service provides each user account with a domain name. Router with DDNS
capability has a built-in DDNS client that updates the IP address information to DDNS service provider
whenever there is a change. Therefore, users can build website or other Internet servers even if they
don’t have fixed IP connection.
Subnetwork or Subnet
Found in larger networks, these smaller networks are used to simplify addressing between numerous
computers. Subnets connect to the central network through a router, switch or gateway. Each individual
wireless LAN will probably use the same subnet for all the local computers it talks to.
IP Address
IP (Internet Protocol) is a layrer-3 network protocol that is the basis of all Internet communication. An IP
address is 32-bit number that identifies each sender or receiver of information that is sent across the
Internet. An IP address has two parts: an identifier of a particular network on the Internet and an
identifier of the particular device (which can be a server or a workstation) within that network. The new
IPv6 specification supports 128-bit IP address format.
MAC
Media Access Control. MAC address provides layer-2 identification for Networking Devices. Each
Ethernet device has its own unique address. The first 6 digits are unique for each manufacturer.
When a network device have MAC access control feature, only the devices with the approved MAC
