IPv4 address exhaustion

Every host on an IP network, such as a computer or networked printer, is assigned an IP address that is used to communicate with other hosts on the same network or globally. Internet Protocol version 4 provides approx. 4.29 billion short scale addresses. However, large blocks of IPv4 addresses are reserved for special uses and are unavailable for public allocation.
There are insufficient publicly routable IPv4 addresses to provide a distinct address to every IPv4 device or service (which include desktop computers, mobile phones, embedded devices, and virtual hosts). IPv6 is the standards-based solution to the IPv4 address shortage, endorsed by all Internet technical standards bodies and network equipment vendors. In addition to other design improvements, it replaces the 32-bit IPv4 address (4.3 billion possible hosts) with a 128-bit address for a capacity of 3.4×1038 hosts.
