Oct 20, 2019 · The concept of tunneling IPv6 traffic over an IPv4 network is a simple one. This is what we’ll do in Packet Tracer: Create IPv6 networks , say, two IPv6 networks (LANs) at two ends of an IPv4 network. Create an IPv6 tunnel through the IPv4 network through which the IPv6 traffic will be routed. Finally configure routing (Both IPv4 and IPv6 ).

The IPv4/IPv6 Basics. The address space is the main difference between IPv4 (32-bit) and IPv6 (64-bit). The text representation has also been changed from a 2-digit partitioning for IPv4 to 4 Jul 13, 2020 · IPv4 IPv6; Size of IP address : IPv4 is a 32-Bit IP Address. IPv6 is 128 Bit IP Address. Addressing method : IPv4 is a numeric address, and its binary bits are separated by a dot (.) IPv6 is an alphanumeric address whose binary bits are separated by a colon (:). It also contains hexadecimal. Number of header fields : 12 : 8 : Length of header Jun 05, 2020 · Smart people had foreseen the problem of IoT vendors' natural growth over time. About a decade ago, IPv6 came into being. It allows for 2^128 possible addresses, compared to IPv4’s 2^32. Musing that "little pockets of IPv4" and some government services hosted on IPv4 are two of the things holding the world back, Hogewoning told The Register:

Important Internet Protocol version 6 (IPv6) is a mandatory part of Windows Vista and Windows Server 2008 and newer versions. We do not recommend that you disable IPv6 or its components. If you do, some Windows components may not function. We recommend that you use “Prefer IPv4 over IPv6” in prefix policies instead of disabling IPV6.

IPv4 over IPv6では、IPv4形式の通信パケットをIPv6形式の通信パケットと見せかけて通信することができます。 ということはつまり？ 上述の「IPv6 IPoEのデメリット」を克服できる ということです。これがIPv4 over IPv6のメリットです。 「IPv4 over IPv6」のデメリット

Example: Configuring an IPv6-over-IPv4 Tunnel There is usually also a preference for IPv6 over IPv4. When offering both protocols the user will start using IPv6 when possible, which avoids the drawbacks mentioned about IPv4 NAT. The downside of supporting two protocols is that it does require some extra effort, but when using the right tools this is not as hard as it might seem.
