For example, a network printer may be assigned a private IP address to prevent rest of the world from printing from it. To allow organizations to freely assign private IP addresses, the NIC has reserved certain address blocks for private use. The following IP blocks are reserved for private IP addresses. In addition to above classful private addresses, The loopback IP address is the address used to access itself.
The IPv4 designated A loopback interface is also known as a virtual IP, which does not associate with hardware interface. On Linux systems, the loopback interface is commonly called lo or lo0. The corresponding hostname for this interface is called localhost.

IPv6 was introduced in to ensure that the world would not run out anytime soon: IPv6 uses bits, resulting in 3. To use the internet, all connected devices must have a public IP address.
An IP address allows two devices—the sender and recipient of internet communications—to find and exchange information with each other. The setup is similar to real-life address systems. For example, if you were to subscribe to a magazine, the magazine distributor the sender would need your address to send you the recipient your copies. The same applies to the internet. Without an IP address, two devices would not be able to find and exchange information with each other. Each computer or device in your home network has a unique private IP address so it can communicate with all the others, but nothing outside of the local network can see them or establish a connection.
Certain ranges of numbers are only available for use as a private IP address. Anytime you visit a website, it can potentially gather even more information about you. You may use 'traceroute' command to find clues to the location of the IP address. The names of the routers through which packets flow from your host to the destination host might hint at the geographical path of the final location.
IP-based Geolocation is mapping of an IP address or MAC address to the real-world geographic location of an Internet-connected computing or a mobile device.
There are a number of commercially available geolocation databases, and their pricing and accuracy may vary. NET and Java programming languages that can be used to retrieve geolocation data from the database. We use a number of commercial databases to offer a free geolocation data on our website. There are also freely available geolocation databases. Vendors offering commercial geolocation database also offer a Lite or Community edition that provides IP-to-Country mappings.
There are companies also offering free web services that can be used to show geolocation of an IP address on your website. Accuracy of geolocation database varies depending on which database you use. The IP whois information is available for free, and determining the country from this database is relatively easy. When an organization requires a block of IP addresses, a request is submitted and allocated IP addresses are assigned to a requested ISP.
