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, …

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.

An IPv6 address in colon-hexadecimal format, h:h:h:h:h:h:h:h , where each h is a hexadecimal value (0-FFFF). An IPv6 address is a 128-bit address separated into eight 16-bit parts. Each part is converted …

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')).

IPv6, with its 128-bit addresses, provides globally unique and hierarchical addressing based on prefixes rather than address classes, which keeps routing tables small and backbone routing efficient.

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 …

The idea is to embed IPv4 tunnel addresses into the IPv6 prefixes so that any domain border router can automatically discover tunnel endpoints for outbound IPv6 traffic.

Subnet masks (IPv4) and prefixes (IPv6) identify the range of IP addresses that make up a subnet, or group of IP addresses on the same network. For example, a subnet can be used to identify all the …

The layout of an IPv6 address is defined in RFC 2373, IP Version 6 Addressing Architecture, available at https://www.ietf.org/rfc/rfc2373.txt. This permits the single use of a double colon to mean one or …

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 …
