RFCs are not the law. You can break them. I use so-called routable/non-private (although not allocated) addresses for my internal network. ISPs route non-routable/private addresses. Specifically, they use such addresses as part of their management network: they assign private addresses in the 10.x.x.x space to routers, modems, etc.
From what I understand, cable-modem providers give a 10.x.x.x address to their cable-modems for management purposes. I believe the last time I had a cable modem, I saw these 10.x.x.x addresses exposed on my Ethernet.
I run traceroute through my tethered cellphone, and find that the phone company assigns 192.168.x.x addresses to routers. nmap scans confirm other machines in that so-called "private" "non-routable" range. I'm sure if you ping the 10.10.167.40, you'll find that it's only a couple hops away. --- On Fri, 4/3/09, Richard Golodner <rgolodner () infratection com> wrote:

Any ideas are welcome and there are no chat programs allowed on our (MY) LAN, so I have ruled that out.
