<para>A boolean. When true, enables IPv4 link-local support.

+ <para>If the specified
+ address is 0.0.0.0
+ (for IPv4) or [::]
+ (for IPv6) a new
+ address range of the
+ requested size is
+ automatically
+ allocated from a
+ system-wide pool of
+ unused ranges. The
+ allocated range is
+ checked against all
+ current network
+ interfaces and all
+ known network
+ configuration files to
+ avoid IP range
+ conflicts. The default
+ system-wide pool
+ consists of
+ 192.168.0.0/16,
+ 172.16.0.0/12 and
+ 10.0.0.0/8 for IPv4,
+ and [fc00::] for

+ functionality is
+ useful to manage a

+ network interfaces
+ with the same network
+ configuration and
+ automatic address
