An Overview of IPv6 Addressing

An Overview of IPv6 Addressing
The IPv6 addressing scheme has been developed to be compatible with the current IPv4 addressing
standard, which allows the new IPv6 networks to coexist with IPv4 networks. IPv6 increases
the size of the address space from 32 bits to 128 bits, which provides
340,282,366,920,938,463,463,374,607,431,768,211,456, or 3.4 × 1038, addresses. IPv6 also
improves routing, security, and quality of service (QoS) features, while simplifying the IP
header. The IPv6 addressing architecture is described in RFC 3513, which defines how the
address space will be utilized.
Let’s talk about how IPv6 addresses are represented.
