Unformatted text preview: x:x:x:x:x, where the 'x's are
one to four hexadecimal digits of the eight 16-bit pieces of the
address. Examples: ABCD:EF01:2345:6789:ABCD:EF01:2345:6789 2001:DB8:0:0:8:800:200C:417A Note that it is not necessary to write the leading zeros
in an individual field, but there must be at least one numeral
in every field (except for the case described in 2.). 2. Due to some methods of allocating certain styles of IPv6 addresses, it will be common for addresses to contain long
strings of zero bits.
containing zero In order to make writing addresses bits easier, a special syntax is available to compress the
zeros. The use of "::" indicates one or more groups of 16 bits of
zeros. The "::" can only appear once in an address.
also be The "::" can used to compress leading or trailing zeros in an address. For example, the following addresses 2001:DB8:0:0:8:800:200C:417A a unicast address FF01:0:0:0:0:0:0:101 a multicast address 0:0:0:0:0:0:0:1 the loopback address 0:0:0:0:0:0:0:0 the unspecified address may be represented as 2001:DB8::8:800:200C:417A a unicast address FF01::101 a multicast address ::1 the loopback address :: the unspecified address 3.
