  1. IPv6 address formats - IBM

    Specify IPv6 addresses by omitting leading zeros. For example, IPv6 address 1050:0000:0000:0000:0005:0600:300c:326b can be written as 1050:0:0:0:5:600:300c:326b.

  2. IPv4 and IPv6 address formats - IBM

    An IPv6 (dual) address combines an IPv6 and an IPv4 address and has the following format: y:y:y:y:y:y:x.x.x.x. The IPv6 portion of the address (indicated with y's) is always at the beginning, …

  3. IPv4-mapped IPv6 addresses - IBM

    These addresses hold an embedded global IPv4 address. They are used to represent the addresses of IPv4 nodes as IPv6 addresses to applications that are enabled for IPv6 and are using AF_INET6 …

  4. Internet Protocol Conventions for IPv4 and IPv6 - IBM

    An IPv6 address is 128 bits. The preferred IP address format has 8 hexadecimal numbers representing 16 bytes (for example, x:x:x:x:x:x:x:x (x = X‘0' - X‘FFFF')).

  5. Using AF_INET6 address family - IBM

    This address format represents the IPv4 address of an IPv4 node to be represented as an IPv6 address. The IPv4 address is encoded into the low-order 32 bits of the IPv6 address, and the high-order 96 …

  6. IP addresses - IBM

    Each server or client on a TCP/IP internet is identified by a numeric IP (Internet Protocol) address. The two types of IP address are the IPv4 (IP version 4) address and the IPv6 (IP version 6) address.

  7. Configuring reverse lookup zones - IBM

    For IPv6 subnets, the format to use in the domain name field is <reverseIP>.ip6.arpa where you invert the IPv6 address, separating each character with a period (.) and removing the netmask.

  8. Specifying connection information - IBM

    IPv6 supports 2 128 addresses written as 8 groups of colon-separated 4 hexadecimal digits, for example, 1001:0dc8:0:0:0:ff10:143e:57ab. The following guidelines apply to IPv6 addresses:

  9. IPv6 address types - IBM

    This information shows the categories of different IPv6 address types, and explains the uses for each of them.

  10. Textual representation of IPv6 addresses - IBM

    IPv4 addresses are represented in dotted decimal format. The 32-bit address is divided along 8-bit boundaries. Each set of 8 bits is converted to its decimal equivalent and separated by periods. In …
