Reference IP concept
What is a referral IP?
A referrer IP address or Internet protocol of reference, is a numerical representation used to identify a team or a website. In other words, it is like a license plate number or an address by which a device or a web portal can be identified and called.
The addresses are made up of four numerical blocks, where each block is separated by a point and said number corresponds to a number from 0 to 255. The reference IPs they can be public or private and, at the same time, dynamic. A dynamic IP address is an IP address that changes every time you restart your computer or device.
The reference IP address may change due to changes in the network, due to the use of the Dynamic Host Configuration Protocol DHCP, which stands for Dynamic Host Configuration Protocol, known as Dynamic IP. For servers, a static or fixed IP is commonly used, that is, it does not change over time so that users can always find them.
For people, it is difficult to remember a referring IP number of a site. This is why domain names were created. Even when the IP address changes, through the Domain Name Server DNS, the domain name is translated to the respective IP address, without affecting the user.

Referral IP Examples
To illustrate how a reference IP works, think about how you send documents from your PC to your home wireless printer.
This is feasible because the printer has a private IP, which your PC has previously detected and which it already has registered as a reference IP within your home private network.
In order for the devices connected to the private network to be able to connect to the outside, with a public network such as the Internet, they require a router.
