Organizations can allocate these bits in any way they desire.</P
><P
>The Interface Identifier must be unique on that network. On
ethernet networks, one way to ensure this is to set the address
to the first three bytes of the hardware address, "FFFE", then the
last three bytes of the hardware address. The lowest significant
bit of the first byte should then be complemented. Addresses are
written as 32-bit blocks separated with a colon, and leading zeros
of a block may be omitted, for example:</P
><P
><B
CLASS="command"
>3ffe:8050:201:9:a00:20ff:fe81:2b32</B
></P
><P
>IPv6 address specifications are likely to contain long strings
of zeros, so the architects have included a shorthand for specifying
them. The double colon (`::') indicates the longest possible string
of zeros that can fit, and can be used only once in an address.</P
