Private IP Addresses: An Ultimate Guide

A private IP address router or other network address translation (NAT) device is the IP address reserved for public IP for internal use.

Private IP addresses conflict with the public IP address, which is public and can not be used in home or corporate networks.

Occasionally, a private IP address is also called a local IP address.

Which IP address is private?
The Internet Assigned Number Authority (INAA) reserves the following IP address blocks for use as a private IP address:

10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.100.1 to 19 2,168,255,255
From above, the first set of IP addresses allows more than 16 million addresses, more than 10 million and more than 65,000 addresses for the final limit.

The second series of private IP addresses is 169, 254.0.0 to 16,254,255,255. However, this address is only for the private IP addressing (APIPA).

In 2012, INAA gave 4 million addresses (100.64.0.0/10) for use in a career-grade NAT environment.

Why is private IP address used?
Rather than leaving the device in the home or business network, each one uses a public IP address that has a limited amount. Private IP addresses, however, provide a fair set of addresses but allow access to the network without the location of the public IP address

For example, consider the standard router on the home network. Most of the routers in homes and businesses around the world, probably you and your closest neighbor, all have an IP address of 19.2168.1.1 and they connect to 192.168.1.2, 19.2168.1.3 for different devices. ... assign (via the so-called DHCP).

It uses the number of routers using the address 19.11.16.1.1 or some ten or several devices in the network share IP addresses with users of other networks because they do not communicate directly to each other

Rather, the use of a network router is used by the public to translate its requests over the network, which can communicate with other public IP addresses and, ultimately, other local networks.

Using a private IP address, the hardware in the given network can communicate with all other devices within that network's boundaries. However, the router must communicate with devices outside the network, then public IP addresses are used for communication.

For example, before you come to this page, your device (a computer, phone, or whatever) uses a private IP address, the router asks you for this page where the public device is displayed. There Once indicated and LifeWeek responded to the deployment of the page, it was downloaded by a public IP address before reaching your router on your device. Then it is available for your personal / local network. Sent to the address

All devices (laptops, desktops, phones, tablets, etc.) can use a private IP address in a private network around the world, which is almost unlimited, which is not a public IP address.

Private IP addresses also provide a mechanism for devices that do not need to be connected to the Internet, such as file servers, printers and others, however, communicate directly to public disclosure with other devices on the network.

Protected IP addresses
The second set of IP addresses which are more restricted is called a reserved IP address. This is similar to a private IP address, so it can not be used for interaction on the Internet, but it is more limited.

The best known reserved IP address is 127.0.0.1. This address is called a loopback address and it is used to check the network adapter or integrated chip. No traffic directed at 127.0.0.1 is sent to local or public internet.

Technically, the full range from 127.0.0.0 to 127.255.255.255 is reserved for loopback purposes, but nothing is displayed except in the real world 127.0.0.1.

Addresses are reserved in the range of 0.0.0.0 to 0.255.255.255, but nothing is done. If you can specify an IP address in this category's device, it will not function properly even though it is installed on the network.
