On the other hand, Facebook's Engineering blog stated that accessing Facebook can become 10 to 15 percent faster over IPv6. Built-in authentication and privacy backingĪ study conducted by security blog Sucuri, where they run series of tests, found that in direct connections, IPv4 and IPv6 deliver the same speed, IPv4 occasionally won the test.The actual quality of service (QoS), also called "flow labeling.".More modest and more significant packet headers format.Built-in network security layer (IPsec).IPv6 allows end-to-end connectivity at the IP layer.NAT (Network Address Translation) is no more required.In IPv6, the size of routing tables is reduced, and it performs routing more efficiently and hierarchically.However, the main difference is that it uses a 128 bit IP address compared to IPv4, which supports 32-bit IP addresses. It functions similar to IPv4, as it provides unique IP addresses to internet-connected devices. IPv6 is the sixth version of the internet protocol and the successor of IPv4. Why prefer IPv6? What are the benefits of IPv6? However, IPv6 doesn't support such a facility. IPv4 supports VLSM (Variable Length Subnet Mask).However, IPv6 practices NDP (Neighbour Discovery Protocol) to map to MAC address. IPv4 practices ARP (Address Resolution Protocol) to map to MAC address.IPv4 supports broadcast, while IPv6 supports multicast routing.In IPv4, you have checksum fields, while IPv6 doesn't have such fields.IPv4 allows twelve header fields, whereas IPv6 allows eight header fields.A dot separates IPv4 binary bits (.), whereas a colon separates IPv6 binary bits (:).
