Details:
This bug report possibly could be more of an RFC clarification than an actual
bug.
AutoIP can assign 169.254.0.0 to 169.254.0.255. Throughout RFC 3927 it does
mention "169.254/16" to indicate all 65536 addresses in the 169.254 subnet,
but notice that section 2.1 states:
"When a host wishes to configure an IPv4 Link-Local address, it selects an
address using a pseudo-random number generator with a uniform distribution in
the range from 169.254.1.0 to 169.254.254.255 inclusive."
This implies that 169.254.0.0 to 169.254.0.255 are not valid link local
addresses.
Thoughts?
