What is the need of dedicated IP address.

Is it need or necessity to have a dedicated IP address for your website and if yes means why. If you just can use a shared IP. Because in shared server the IP is common for all the website hosted in that particular server.

Using an dedicated IP address provides with a wide or certain advantages, before going to that let’s start with the definition first,

What is a Dedicated IP address?

IP stands for Internet Protocol and is defined as a unique address assigned to each computer that is connected to a certain network. Internet Protocol address plays the role of a unique identifier that is used to provide valid location of a machine or a website in a given network. IP addresses are usually written and displayed in human-readable notations for your simplicity let us consider your IP address is like your residence address, your home is your website.

Then what is the difference between the IP’s.

Shared vs Dedicated IP Addresses

To understand the distinction between shared and dedicated IP addresses, we need to look at the foundation – the IP address.

IP stands for Internet Protocol, which is how data is routed from place to place across networks. The IP address most commonly still used today is IPv4, which has 4 sets of 8-bit fields as the format. 

Examples of IP addresses in this format are:

• 8.8.8.8
• 192.168.0.1
• 127.0.0.1

For your understanding here below view the diagram,

We can only assign an IP address to one unique device in a network. For instance, if a network has three devices, it will be necessary to have three IP addresses – one assigned to each. Because of the format they are in, the number of IP addresses available is finite. 

However, nothing stops you from sharing a single IP address among multiple domains. For example, web hosting companies use this method to offer shared hosting.

In shared hosting, hundreds of user accounts utilize the same physical server. To keep the service affordable, hosts may share one or two IP addresses for all users on the machine. In instances like this, we call it a shared IP address.

The biggest problem with IP addresses is the finite number combinations that a provider can assign.

This limitation has made IP addresses somewhat of a valuable resource. When supply can’t meet demand – prices naturally increase. Because of this, dedicated IP addresses are costlier than any shared IP.
