An Internet Protocol (IP) address is a unique number assigned to every device on a network. Just as a street address determines where a letter should be delivered, an IP address identifies computers on the Internet. Network devices use IP addresses to communicate with each other.
The Internet uses DNS (Domain Name System) to enable people to use words instead of numbers for Internet addresses. You can think of DNS as an Internet address book, mapping domain names to IP addresses.
When you type a URL into your browser, your browser looks up that domain name in DNS. For example, if you type www.abijita.com into your browser, your browser would ask DNS for Abijita’s IP address. DNS would return the IP address assigned to Abijita’s domain name (104.37.174.139). Your browser then connects to that IP address. Here, we are going to learn the differences between Elastic IP, Static IP & Public IP.
Elastic IP
An Elastic IP address is a static IPv4 address designed for dynamic cloud computing. Within the AWS infrastructure, customers have virtual private clouds (VPCs). Within the VPCs, users have instances. The Elastic IP address is what is used to advertise the data within the instance to the public internet. With an Elastic IP address, you can mask the failure of an instance or software by rapidly remapping the address to another instance in your account.
An Elastic IP address is a public IPv4 address, which is reachable from the internet. If your instance does not have a public IPv4 address, you can associate an Elastic IP address with your instance to enable communication with the internet.
Static IP?
A static IP address is an IP address that was manually configured for a device, versus one that was assigned by a DHCP server. It’s called static because it doesn’t change. It’s the exact opposite of a dynamic IP address, which does change.
Routers, phones, tablets, desktops, laptops, and any other device that can use an IP address can be configured to have a static IP address. This might be done through the device giving out IP addresses (like the router) or by manually typing the IP address into the device from the device itself.
The IP address that is assigned to you is most likely a dynamic IP address. This is the most common for residential customers. This means that the IP address changes frequently, which provides customers and ISPs cost savings.
Public IP
A Public IP address is how the internet identifies you. A public IP address is the IP address that communicates your internet connected device to the public internet.
A public IP address is the address that is assigned to a computing device to allow direct access over the Internet. A web server, email server and any server device directly accessible from the Internet are candidate for a public IP address. A public IP address is globally unique, and can only be assigned to a unique device.

We are very sorry to let you know that we cannot help you in this matter. You have to contact your service provider yourself to assign you the static IP.
