In the absence or failure of static or stateful (DHCP) address configurations, an operating system may assign an IP address to a network interface using state-less auto-configuration methods, such as Zeroconf. This provides instant and automatic communication between all IPv6 host on a link. An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. In 1981, the Internet addressing specification was revised with the introduction of classful network architecture.[2] Classful network design allowed for a larger number of individual network assignments and fine-grained subnetwork design.

This development is referred to as IPv4 address exhaustion. The CIDR notation for the same IP address and subnet is 192.0.2.1/24, because the first 24 bits of the IP address indicate the network and subnet.

The intent of the new design was not to provide just a sufficient quantity of addresses, but also redesign routing in the Internet by more efficient aggregation of subnetwork routing prefixes.

Online Tech Tips Online-tech-tips.com. RFC 4193 reserves the routing prefix fc00::/7 for this block which is divided into two /8 blocks with different implied policies. For this purpose, an IP address is logically recognized as consisting of two parts: the network prefix and the host identifier, or interface identifier (IPv6). Filling the void, Microsoft created an implementation that is called Automatic Private IP Addressing (APIPA).

This process is usually transparent to the user unless the computer warns about an IP address conflict on the network (two computers with the same IP address). Is there a major hardware component to making this work? It attaches an "electronic return address" to all your online requests and activity for you. Three non-overlapping ranges of IPv4 addresses for private networks were reserved in RFC 1918.

Private address prefixes may not be routed on the public Internet.
