========================================

 

The size of the IPv6 address is 128 bits. The preferred IPv6 address is:XXXX: xxxx, Where eachXIs a 4-digit hexadecimal number. IPv6 address ranges from0000: 0000: 0000: 0000: 0000: 0000: 0000: 0000ToFFFF: FFFF.

IPv4 addresses are composed of 32-bit binary codes. The format is XXX. XXX, where X represents a three-digit binary number.

In addition to the preferred format, the IPv6 address can be specified in two other short formats:

• Omitted leading zero 
  The IPv6 address is specified by omitting the leading zero. For example, IPv6 address1050: 0000: 0000: 0000: 0005: 0600: 300C: 326bWritable1050: 0: 0: 0: 5: 600: 300C: 326b.
• Double colon 
  By using the double colon (::In place of a series of zeros to specify IPv6 addresses. For example, IPv6 addressFf06: 0: 0: 0: 0: 0: 0: C3WritableFf06: C3. Only one double colon can be used in an IP address.

An optional format of an IPv6 address combines a colon with a dot notation. Therefore, an IPv4 address can be embedded into an IPv6 address. Specify the hexadecimal value for 96 digits on the leftmost side and the decimal value for 32 digits on the rightmost side to indicate the embedded IPv4 address. When working in a hybrid network environment, this format ensures compatibility between IPv6 nodes and IPv4 nodes.

The two types of IPv6 addresses use this optional format:

• IPv6 address mapped through IPv4 
  This type of address is used to represent an IPv4 node as an IPv6 address. It allows IPv6 applicationsProgramDirectly communicates with an IPv4 application. For example,0: 0: 0: 0: 0: FFFF: 192.1.56.10And: FFFF: 192.1.56.10/96(Short format ).
• IPv4-compatible IPv6 addresses 
  This type of address is used for tunneling. It allows IPv6 nodes to communicate with each other through the IPv4 infrastructure. For example,0: 0: 0: 0: 0: 0: 192.1.56.10And: 192.1.56.10/96(Short format ).

All these formats are valid IPv6 address formats. Specify any of these IPv6 address formats in the iseries navigator.
