4.2.3 IPv6 Configuration

Internet Protocol version 6 (IPv6)

is the next-generation Internet Protocol version designated as the successor to IPv4, the

first implementation used in the Internet that is still in dominant use currently[update]. It is an Internet Layer protocol for

packet-switched internetworks. The main driving force for the redesign of Internet Protocol is the foreseeable IPv4 address

exhaustion.

IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address. This expansion provides

flexibility in allocating addresses and routing traffic and eliminates the primary need for network address translation (NAT),

which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.

IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and

network renumbering (prefix and router announcements) when changing Internet connectivity providers. The IPv6 subnet size

has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic

mechanism for forming the host identifier from Link Layer media addressing information (MAC address).

Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security (IPsec) was originally

developed for IPv6, but found widespread optional deployment first in IPv4 (into which it was back-engineered). The IPv6

specifications mandate IPsec implementation as a fundamental interoperability requirement.

The address is an eight-part hex address separated by colons (" :"). Each part n can equal a 16-bit number and is eight parts

long, providing a 128-bit address length (16 * 8 = 128),

Format of IPv6 Addresses are

n:n:n:n:n:n:n:n

n = 4 digit hexadecimal integer, 16 * 8 = 128 address.

The Configured column is used to view or change the IPv6 configuration. The Current column is used to show the active IPv6

configuration. The screen in

appears.
