I'm sure you know all this, as you wouldn't have any other reason to be using addresses from that range. Basically it's an IPv4 equivalent to the IPv6 rtadv/rtsol thing. The addresses from that range are non-routable, similarly to the RFC 1918 private ranges, but that's just a convention for RFC1918, and I can see there is special code to handle RFC 3927 eg in: http://lists.freebsd.org/pipermail/svn-src-head/2009-September/009999.html Are you using avahi-autoipd ?
