When the Internet exploded, having only 32 bits to identify a unique Internet address caused people to panic that we'd run out of IP addresses. Depending on the class derived, the network identification was based on octet boundary segments of the entire address. In 1981, the Internet addressing specification was revised with the introduction of classful network architecture. Classful network design allowed for a larger number of individual network assignments and fine-grained subnetwork design. When the link-local IPv4 address block was reserved, no standards existed for mechanisms of address autoconfiguration.
This address type was abandoned and must not be used in new systems. Addresses starting with fe80:, called link-local addresses, are assigned to interfaces for communication on the attached link. The large number of IPv6 addresses allows large blocks to be assigned for specific purposes and, where appropriate, to be aggregated for efficient routing. May 2011 . Uses of dynamic address assignment IP addresses are most frequently assigned dynamically on LANs and broadband networks by the Dynamic Host Configuration Protocol (DHCP).
