Re: question about socket with link local addr

Hi,m Stuart!

Please correct me if I'm wrong, but isn't this question about a generic
socket problem?

I think if I am using ethernet phy and a 10.1.1.157 address with a
relatively standard netmask of 255.255.255.0 and I create a socket, using
Windows stack or Linux stack, to IP address 169.254.80.220, and I am using a
DHCP router, doesn't that packet get forwarded to the router's MAC and then
go nowhere?

And, if I do the same thing but have no router, doesn't the current Windows
and Linux stack just eat the packet and it goes nowhere?  Since there's no
router MAC to forward the packet?

Wasn't there a substantial discussion about this issue?  And wasn't the
resolution that we don't have to care about this situation?

And isn't this a generic socket stack issue, not related to Apple?

Again, please correct me if I'm wrong.

Thanks

Jim Busse
