CS402: Computer Communications and Networks

IPv4 addresses are notated using a dotted decimal format. The current IPv4 system lacks sufficient addresses for today's device volume. After you watch this video, can you explain the difference between public and private IPv4 address ranges and their allocation strategies? What are the functions of special addresses like 0.0.0.0, 127.0.0.1, and 255.255.255.255? Can you think of scenarios where IPv4 addresses are autoconfigured versus when they are leased? To better understand the autoconfiguration process, consider reviewing RFC 3927, which formalizes this protocol.
