4 BASIC IP NETWORKING
IP = Internet Protocol
IP stands for Internet Protocol. In an IP network, every device has a unique IP Address (For
example: 192.168.1.35) to identify itself. There are two ways of assigning an IP address to a
PC or Router: Static and Automatic (DHCP). Static IP addresses are keyed-in manually, while
Dynamic IP’s are distributed by a DHCP Server.
Ports
Every packet of traffic is identified by its Source and Destination Addresses, which would
ensure that the packet arrives at the correct destination. A Port Number is also embedded in
each packet; to identify which software application that generated and uses that packet.
Therefore, if it blocks a certain port number, it denies the particular software from using the
connection.
Static IP Address
Static IP addressing ensures that the device will always have the same IP address. Static
addressing is commonly used for your servers.
Dynamic IP Address
A dynamic IP address is one that is automatically assigned to a PC. These IP addresses are
“dynamic” because they are only temporarily leased to the PC when it connects to the
network. This is the most convenient and common way of managing IP addresses in a
network. The Server that manages this pool of IP addresses is called the DHCP Server. The
product has a DHCP Server built-in to simplify the network management.
