IPv6 addresses are assigned to organizations in much larger blocks as compared to IPv4 address assignments—the recommended allocation is a / 48 block which contains 2 80 addresses, being 2 48 or about 2.8 × 10 14 times larger than the entire IPv4 address space of 2 32 addresses and about 7.2 × 10 16 times larger than the / 8 blocks of IPv4 ...
If IPv4 is still used in the local area network (LAN), however, and the ISP can only provide one public-facing IPv6 address, the IPv4 LAN addresses are translated into the public facing IPv6 address using NAT64, a network address translation (NAT) mechanism. Some ISPs cannot provide their customers with public-facing IPv4 and IPv6 addresses ...
In 2018, it appeared that all Wireless LTE devices in the network had only IPv6 addresses and no IPv4 gateway, IP address and DNS servers. Bell Canada supports IPv6 on their wireless mobility network, but not residential Fibe Internet services (DSL or FTTH).
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [ 1 ] [ 2 ] IP addresses serve two main functions: network interface identification , and location addressing .
An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [ 2 ] (routable only within the scope of private networks, but not the global IPv6 Internet).

The area identifiers are commonly written in the dot-decimal notation, familiar from IPv4 addressing. However, they are not IP addresses and may duplicate, without conflict, any IPv4 address. The area identifiers for IPv6 implementations (OSPFv3) also use 32-bit identifiers written in the same notation.
