The first few bits of an [IPv6] address which tell a host what kind of address it is.

<?plugin OldStyleTable border=0
| <tt>0000&#160;0000</tt>          | Used for things like [IPv6] compatible [IPv4], loopback and unspecified addresses (1/256th of the address space)
| <tt>001</tt>                     | Aggregatable Global Unicast Addresses (1/8 of the address space)
| <tt>1111&#160;1110&#160;10</tt>  | [Link-Local|LinkLocal] Unicast Addresses (1/2024 of the address space)
| <tt>1111&#160;1110&#160;11</tt>  | [Site-Local|SiteLocal] Unicast Addresses (1/2024 of the address space)
| <tt>1111&#160;1111</tt>          | [Multicast|MultiCast] Addresses (1/256 of the address space)
?>

Almost all the other address space is unallocated or reserved.

See [IPv6Addressing] for more information.
