Networking Protocols

The IP addresses are of two types:

• Static IP Address


• Dynamic IP Address

DHCP server layout

Static IP Address - Address that is obtained manually. The user / supervisor of the system / network assigns this address. This IP adress is not variable address relatively stays the same at each login to the network.

Dynamic IP Address - An address that is obtained from an entity called DHCP Dynamic Host Configuration Protocol server which provides the system loging onto the network with an IP address. This IP address may be variable from each instance of login of the system into the network.

APIPA - (Automatic Private IP Addressing) 169.254.X.X where X is any number from 1 to 254
In case the network does not have a DHCP server , the OS automatically assigns the system with an IP Address. This IP address cannot be used to connect to the internet. This is a Dynamic IP Address

IP Addressing Structures

IP Address Structure : aaa.bbb.ccc.ddd

where :

• aaa.bbb is the Network Part of the IP Address
• ccc.ddd is the Host Part of the IP Address
