[LBo] Link-local.

[Geoff Jones]

I have a small home network using a wired/wireless router as dhcp server.
On my deb etch machine, I recently noticed I have 2 ip  addresses -
192.168.x.x and 169.254.x.x .
A search revealed the second as a "link-local". I read that link-local was to 
allow networking where there is no dhcp server? This machine is wired to the 
router and seems to use the 169 address to link to the other wired machine 
and use 192 for wireless connections ( I think ) - despite having a dhcp 
assigned address?
I wondered if some-one could explain the reasons / configuration / advantages 
or disadvantages of this behaviour?
Thanks,

Geoff.

p.s. I too decided to drop Iceweasel + use firefox direct from Mozilla in 
order to get immediate security updates - first I'd seen of the Deb v. 
Mozilla debate - seems a pity to have a fork in such a successful piece 
of "free" software!
