Addressing Scheme:

Internet addresses are used to access different computers on the internet. Each computer on the internet has a unique address. This address is used to establish a connection with that computer. There are two types of addressing schemes on internet

1. IP Addressing: IP address is a unique number that refers to a computer connected to the internet. IP stands for Internet Protocol. This address is a 32 bit number. It consists of four numbers separated by period. Each number is between 0 to 255. These numbers are known as octets. like 192.168.1.1
2. DNS Addressing: IP address is difficult to remember for the users. All servers on the internet also have human readable name. It is known as domain name. A domain name consists of text instead of number. It is easier to remember a domain name than IP address. For example www.hotmail.com is a permanent and human readable name. It is easier to remember than IP address. It has two parts

• Hot name
