![]() With Dual-IP stacks, your computers, routers, switches, and other devices run both protocols, but IPv6 is the preferred protocol. The double colon (::) can be used once in the text form of an address, to designate any number of 0 bits. The text form of the IPv6 address is xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx, where each x is a hexadecimal digit, representing 4 bits. So there are more than enough IPv6 addresses to allow for Internet devices to expand for a very long time. The number of IPv6 addresses is 1028 times larger than the number of IPv4 addresses. IPv6 utilizes 128-bit Internet addresses. That may seem like a lot, but all 4.29 billion IP addresses have now been assigned, leading to the address shortage issues we face today. ![]() That means it can provide support for 2^32 IP addresses in total â around 4.29 billion. IPv4 uses a 32-bit address for its Internet addresses. Built-in authentication and privacy support.True quality of service (QoS), also called "flow labeling".No more NAT (Network Address Translation).However, it does have one significant difference: it utilizes a 128-bit IP address. It functions similarly to IPv4 in that it provides the unique IP addresses necessary for Internet-enabled devices to communicate. IPv6 (Internet Protocol version 6) is the sixth revision to the Internet Protocol and the successor to IPv4. Why Support IPv6? What are the benefits of IPv6? ![]() To send data from one computer to another through the web, a data packet must be transferred across the network containing the IP addresses of both devices. Whenever a device accesses the Internet, it is assigned a unique, numerical IP address such as 99.48.227.227. It is the underlying technology that makes it possible for us to connect our devices to the web. IPv4 stands for Internet Protocol version 4. The original IP address scheme, called IPv4, is running out of addresses due to its widespread usage from the proliferation of so many connected devices. Every computer, mobile phone, home automation component, IoT sensor and any other device connected to the Internet needs a numerical IP address to communicate between other devices. IPv6 is the next generation Internet Protocol (IP) address standard intended to supplement and eventually replace IPv4, the protocol many Internet services still use today. ![]()
