Dynamic IP address : A dynamic IP address is an IP address that is automatically assigned to a client station (computer, network equipment, etc.) in a TCP/IP network. Dynamic IP address is typically assigned by a DHCP server, which can be a computer on the network or another piece of hardware, such as router. A dynamic IP address may change every time your computer connects to the network
DHCP (Dynamic Host Configuration Protocol) : DHCP is software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. DCHP eliminates troublesome job to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also found in network devices such as routers. Most of Cable Modem for Internet access uses DHCP Public IP address and Private IP address : Public IP address is an IP address which can be identified uniquely in Internet world. All IP addresses excluding private IP addresses are public IP addresses. Private IP addresses range from 10.0.0.0 until 10.255.255.255, and from 192.168.0.0 to 192.168.255.255. Generally speaking, private IP addresses are used in local area network which are hidden from the Internet world. Also, when public IP addresses not enough, private IP addresses are used while sharing global IP addresses
Router : Router is a network hardware which routes either Private or Public IP address to Public network so that network device between private IP network and Public IP network can communicate over the network. Router has NAT (Network Address Translation) function and through this function Public IP address will be mapped into private IP network so that Network device in the private IP address can be added from Internet.
Hub : Hub is a hardware which relay transmission between Router and Network device. There are two types of Hub. One is Dummy hub and the other one is Switching hub. Note that Hub will be used in the local network only.
NAT (Network Address Translation) : Network Address Translation (NAT) translates multiple IP addressed on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private
