Unlike the public address, local people can not access the internet directly
A private IP address is an IP address that is reserved for internal use behind a router or other Network Address Translation (NAT) device, except for the public.
Private IP addresses are contrary to the public IP address, which are public and can not be used within the home or business network.
Occasionally a private IP address is also known as a local IP address.
Which IP addresses are private?
The Internet Assigned Number Authority (IANA) reserves the following IP address blocks for use as private IP addresses:
From the top, the first set of IP addresses allows for more than 16 million addresses, for more than 1 million and more than 65,000 for the final category.
Another limit for private IP addresses is 169.254.0.0 to 169.254.255.255, but those addresses are only for the automatic private IP address (APIPA).
In 2012, IANA allocated 4 million addresses of 100.64.0.0/10 for use in the carrier-grade NAT environment.
Why private IP address is used?
Instead of placing a device inside a home or business network, each public IP address, one of which is a limited supply, private IP addresses provide a completely different set of addresses that still allow access to a network Giving, but without the location of a public IP address .
For example, let's consider a standard router on a home network. Most router in homes and businesses around the world, maybe you and your next door are neighbors, everyone has an IP address of 192.168.1.1, and for different devices connecting 192.168.1.2, 192.168.1.3, ... Assign (via something called DHCP).
It does not matter how many routers use the ip address 192.168.1.254, 192.168.1.1 or how many dozens or hundreds of devices within the network share IP addresses with users of other networks because they are not communicating directly with each other Are.
Instead, the devices in a network use the router to translate their requests through a public IP address, which can communicate with other public IP addresses and ultimately the other local network.
A hardware within a specific network that is using a private IP address can communicate with all other hardware within the boundaries of that network, but a router will be required to communicate with devices outside the network , After which the public IP address will be used to communicate.
For example, before landing on this page, your device (this is a computer, phone or whatever), which uses a private IP address, has requested this page through a router, in which one Public IP Address Once the request was made and LifeWeek responded to the delivery of the page, it was downloaded to your device via a public IP address before reaching your router, after which it has access to your device. Reached your personal / local address for
All devices (laptops, desktops, phones, tablets, etc.) which are contained in the private network around the world, can use a private IP address with almost no border, which can not be said for public IP address.
Private IP addresses also provide a method for those devices which do not require contact with the Internet, such as file servers, printers, etc., yet communicating with any other device without having to contact the public directly.
Reserved IP addresses
Another set of IP addresses that are also restricted is called reserved IP addresses. These are similar to the private IP address, which they can not use for large internet communication, but they are even more restrictive.
The most famous reserved IP is 127.0.0.1. This address is called loopback address and it is used to test network adapter or integrated chip. No traffic addressed at 127.0.0.1 is sent to the local network or the public Internet.
Technically, the entire range of 127.0.0.0 to 127.255.255.255 is reserved for loopback purposes, but you will almost never see 127.0.0.1 used in the real world.
Addresses are also reserved in the range of 0.0.0.0 to 0.255.255.255 but do not do anything. If you are able to assign an IP address to any device in this category, then it will not work properly on where it is installed on the network.
How to find your personal IP address
Knowing your personal IP address is only helpful in specific, and there are rare conditions for most people.
If you want to connect a computer to another on your network, such as with a mapped network drive, you can do so through its local IP address.
