Addressing [ Internet Protocol version 4(IPv4) ] lecture 02

Описание: Addressing
Decomposition of the quad-dotted IPv4 address representation to its binary value
IPv4 uses 32-bit (four-byte) addresses, which limits the address space to 4294967296 (232) addresses. This limitation stimulated the development of IPv6 in the 1990s, which has been in commercial deployment since 2006.

Because of the demand of the growing Internet, the small address space finally suffered exhaustion on February 3, 2011, after having been significantly delayed by classful network design, Classless Inter-Domain Routing, and network address translation (NAT).

IPv4 reserves special address blocks for private networks (~18 million addresses) and multicast addresses (~270 million addresses)
