IP Address

IP address specifies Internet Protocol. Every device connected with a public Internet is assigned a unique number known as an IP address. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255.For Example .The four numbers in an IP address are used in different ways to identify a particular network and a host on that network.The IP address is devided into 3 classes.

Let us take the example of this IP address

Class A-A Class Ip address is like 1

Class B-B Class IP address is like 1.150

Class C-C Class IP address is like 1.150.24

C class IP address are commonly used in small and middle level business.

Class D and Class E IP address:These two IP addresses are very different than first three classes.

Two types of IP address are there.

  • Shared IP
  • Dedicated IP

Shared IP Address: One IP address is hosted by several domains.

Dedicated IP Address: One IP address is hosted by one IP address i.e unique IP address.

Shared IP is devided again in two categories:

  • Static IP address
  • Dynamic IP address

Static IP address:

A static IP address is fixed IP address.If yourInternet service provider gives you a static IP address,You will always use the same IP address.Server usually have static IP addresses,so they can always be sound at the same location.

Dynamic IP Adress: A dynamic IP address changes each time you connect to your Internet Service Provider (ISP). This allows ISPs to keep a pool of addresses available to subscribers. If you disconnect from the ISP, your address is returned to the pool, becoming available to the next computer that connects.

It is better to use Dedicated IP address for your website.
