Unformatted text preview: imes more convenient when dealing with a mixed environment of IPv4 and IPv6 nodes is x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values of the six high-order 16-bit pieces of the address, and the 'd's are Hinden [Page 4] Standards Track RFC 4291 February 2006 IPv6 Addressing Architecture the decimal values of the four low-order 8-bit pieces of the address (standard IPv4 representation). Examples: 0:0:0:0:0:0:13.1.68.3 0:0:0:0:0:FFFF:129.144.52.38 or in compressed form: ::13.1.68.3 ::FFFF:129.144.52.38 2.3. Text Representation of Address Prefixes The text representation of IPv6 address prefixes is similar to the way IPv4 address prefixes are written in Classless InterDomain Routing (CIDR) notation [CIDR]. An IPv6 address prefix is represented by the notation: ipv6-address/prefix-length where ipv6-address listed is an IPv6 address in any of the notations in Section 2.2. prefix-length the is a decimal value specifying how many of leftmost contiguous bits of the address comprise the prefix. For example, the following are legal representations of the 60-b...
