What is an IPv6 Address? - IoT Agenda

WebIPv6 is a 128-bit IP address which supports 2^128 Internet addresses in total. The use of IPv6 not only solves the problem of limited network addresses resources but also resolves the barriers for multiple access devices to connect to the Internet. An IPv6 address could be written like this: 3ffe:1900:fe21:4545:0000:0000:0000:0000. Features of IPv6 WebCurrently IPv6 provides support for QoS marking via a field in the IPv6 header. Similar to the type of service (ToS) field in the IPv4 header, the traffic class field (8 bits) is available for use by originating nodes and/or forwarding routers to identify and distinguish between different classes or priorities of IPv6 packets.
