ISP hijacks invalid URLs—sometimes

NetworkFilter: I have a bizarre and arcane-seeming problem with my home network, the Internet, and my ISP's DNS. Invalid URLs are being redirected to the ISP's search page—in some cases.

If I type in a partial URL like "amazon", normally I'd expect my browser to figure out that I meant amazon.com and go there. And indeed, it worked that way until about two weeks ago.
At that point (with no changes at my end), I started getting redirected to a special page run by my ISP (grandecom.com) that attempts to monetize my laziness by showing me ads. I realize there's been a lot of this kind of thing with a lot of different ISPs lately.
I have two Macs running 10.5, connected via cat-5, and one Mac running 10.4 connected via wifi, all running into the same old-ish Netgear router (which has current firmware). What I've just figured out is that the wifi-connected Mac does not encounter this redirect; when I connect any of my computers directly to the cable modem, I also don't encounter it.
I've spoken to my ISP's tech support a couple of times. One guy had never even heard of this redirect page and expressed surprise that it exists. The other had heard of it, but claimed there hadn't been a lot of complaints relating to it. And because the problem went away when I took my router out of the loop, he's inclined to blame it.
Clearly the ISP's DNS is implicated, and I am not satisfied with this response, or lack of solution. I'm wondering if anyone has encountered anything like this, or can shed light on it.
