169.254/16 is reserved for Linklocal addresses (not just point-to-point
adresses)

zaphod 14 whois -h whois.arin.net 169.254.1.1
IANA (NETBLK-LINKLOCAL)
   Internet Assigned Numbers Authority
   4676 Admiralty Way, Suite 330
   Marina del Rey, CA 90292-6695
   US

   Netname: LINKLOCAL
   Netblock: 169.254.0.0 - 169.254.255.255


and yes this is IANA approved, and IETF drafts are being circulated.
http://www.ietf.org/internet-drafts/draft-ietf-zeroconf-ipv4-linklocal-05.txt

This (along with a few other things like multicast DNS) is being
called "Zeroconf" now.

p.s.  there is also a block of addresses reserved for exchange points
      (198.32/16)
