About IPv6 Support
IP version 6 (IPv6) handles issues that were not around decades ago when IPv4 was created
such as running out of IP addresses, fair distributing of IP addresses, built-in quality of service
(QoS) features, better multimedia support, and improved handling of fragmentation. A bigger
address space, bigger default packet size, and more optional header extensions provide these
features with flexibility to customize them to any needs.
IPv6 has 128-bit addresses compared to IPv4’s 32-bit addresses, effectively eliminating
address exhaustion. This new very large address space will likely reduce the need for network
address translation (NAT) since IPv6 provides more than a billion IP addresses for each person
on Earth. All hardware and software network components must support this new address size,
an upgrade that may take a while to complete and will force IPv6 and IPv4 to work side-by-side
during the transition period.
