IP address - static vs dynamic, public vs private, shared vs reseller

An IP address is the location of a computer on the internet.

Example: 123.45.67.89

Here are some terminologies for IP addresses.

A class - the first number of the IP
B class - the second number of the IP
C class - the third number of the IP
D class - the fourth and last number of the IP

Static means the IP address never changes as long as you stay with the same provider or same server.
Dynamic means the IP address can change from time-to-time.

Public means the IP address can be visited from any computer in the world.
Private means the IP address can only be used by those on the same network.

Shared means other people use your IP address for their connection or sites.
Dedicated means no one else uses your IP address for their connection or sites.

The difference between shared and dedicated IP addresses

Each computer connected to the Internet is assigned a unique IP address for the purposes of communication. An IP address is a 32-bit numeric address usually expressed as 4 numbers from 0-255 separated by dots, for example 192.168.0.123. There are billions of addresses possible, however, the number is finite.

In the Web hosting industry there are two types of IP address

Dedicated IP address
means that a website has its own IP address. Whether you type in your URL or the numeric form of its IP address, both will bring you to the same domain.

Shared IP address
means that multiple websites share the same address. Web servers can determine by the domain entered in a user's browser which website is being requested. Typing in the IP address will bring you to some kind of generic page instead of the specific site you want.

Due to the rapid increase of the number of registered domain names and the finite number of IP addresses, Web hosting providers are forced to use shared IP's when possible. In fact, hundreds of websites often share the same address. Static IP hosting is no longer the norm and usually costs more.
