Given an Ethernet LAN with a Cable Modem, Router, switches and computers.
Should I give each computer a fixed IP address or
let them Obtain an IP address automatically.
One book on DSL claimed that using automatic address allocation was
somewhat more secure. The claim was that any little net vandal out
there trying to hijack your system had a slightly harder time if you
used automatic allocation because he would not have a single ip
address to hammer on all day long, the address might keep changing
and he wouldn't know for sure what one to hammer on.
Given all the other gaping security holes in software, I'm not sure
how much, if any, this really buys you.
I actually began asking if I could buy a little box with a connector
on each end and a toggle switch on top. When I wasn't going to be
using the net for the next 12 hours I would just flip the switch
and that would disconnect the net cable. Let's see some little net
vandal figure out a way to flip that switch using a Microsoft bug.
Unfortunately I haven't found a supplier for this toggle switch box.
And plugging and unplugging the cable a few dozen times would
probably end up ruining either the cable or the jack.
