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.
