<para>When the mode is set to <literal>static</literal>, an IPv6 address must be

specified after a colon (<literal>:</literal>), and the lower bits of the supplied

(RA) message to form a complete address. Note that if multiple prefixes are received in an
|

RA message, or in multiple RA messages, addresses will be formed from each of them using
|

the supplied address. This mode implements SLAAC but uses a static interface identifier
|
||||
instead of an identifier generated by using the EUI-64 algorithm. Because the interface
|
||||
identifier is static, if Duplicate Address Detection detects that the computed address is a
|
||||
duplicate (in use by another node on the link), then this mode will fail to provide an
|

address for that prefix. If an IPv6 address without mode is specified, then

<literal>static</literal> mode is assumed.</para>

identifier is generated only when a prefix received in an RA message matches the supplied

<para>If no address generation mode is specified (which is the default), or a received

mode, then the EUI-64 algorithm will be used to form an interface identifier for that

prefix. This mode is also SLAAC, but with a potentially stable interface identifier which

does not directly map to the interface's hardware address.</para>

<para>Note that the <literal>prefixstable</literal> algorithm uses both the interface

name and MAC address as input to the hash to compute the interface identifier, so if either
