From a historical perspective, originally all addresses other than the loop back addresses were public and companies were assigned a range. For large companies, they were given a class A address which allowed them to have many unique addresses. Private IPv4 addresses. Private IPv4 addresses (also referred to as private IP addresses in this topic) are not reachable over the Internet, and can be used for communication between the instances in your VPC. When you launch an instance into a VPC, a primary private IP address from the IPv4 address range of the subnet is assigned to the In the right-pane, your Public IP Address will be listed next to Router Entry and Private IP Address will be listed as IPV4 Address. 3.

IPv6 Addressing and Subnetting – TutorZine Then, within the class A, B, and C address range, the Internet Assigned Numbers Authority (IANA) and the Internet Corporation for Assigned Names and Numbers (ICANN) reserve most of the addresses as public IPv4 addresses, with a few reserved as private IPv4 addresses. IPv6 does not use any concept like the classful network concept used by IPv4.
NAT combined with private IPv4 addresses, has proven to be a useful method of preserving public IPv4 addresses. A single, public IPv4 address can be shared by hundreds, even thousands of devices, each configured with a unique private IPv4 address. Without NAT, the exhaustion of the IPv4 address space would have occurred well before the year 2000.
Internet Protocol Version 4 (IPv4) is the fourth generation of IP addressing technology.
