I upgraded the firmware on my Netgear router today and it wouldn't let me use the LAN IP I usually use for it, 10.0.1.1, because it thinks my ISP uses that subnet, because I set the router to read from my own internal DNS. Took me awhile to figure out why it thought what it did, because it didn't occur to me that it would care what DNS addresses I gave it.
