To create a much larger address space and relieve a projected future shortage of IP addresses, IPv6 was created. IPv6 addresses consist of 128 bits, instead of 32 bits, and include a scope field that identifies the type of application suitable for the address. IPv6 does not support broadcast addresses, but instead uses multicast addresses for broadcast. In addition, IPv6 defines a new type of address called anycast.
On devices in secure context, IPv6 is disabled and must be explicitly enabled.
