Private IP addresses are a reserved set of addresses that serve internal networks exclusively. Devices inside this local net can communicate exclusively without being exposed to the internet directly. If you wish to know, ‘What is private IP addresses’, you must know that these are defined by the IANA (Internet Assigned Numbers Authority). They are private in that they do not propagate onto the public internet. Thus, they require translation of IP Addresses through Network Address Translation (NAT) to reach external networks. Essentially, the reason private IP uses are so common is they conserve limited IPv4 space and build up security by keeping hosts off the internet safe from external threats. There are three principal classes: Class A starting from 10.0.0.0 to 10.255.255.255, Class B from 172.16.0.0 to 172.31.255.255, and Class C from 192.168.0.0 to 192.168.255.255. These addresses are dominant in homes, offices, and enterprise environments for internal linking of computers, printers, routers, and smart appliances. Each network worldwide can use private address ranges, too, but relies on NAT to communicate with other external servers. Whereas public IP addresses are unique and allocated by ISPs, private IP addresses are a less costly and safer method to manage links internally within a network. With demand constantly rising for devices that are networked, private IP addresses play a very significant role in the efficient and scalable management of network infrastructure, too.
