The only addresses router will not forward is the local address segment used by the LAN. It has no way of knowing what addresses are being used external to itself. There is a lot of confusion about RFC 1918 private addresses. They are private in so far as they are not used on the public Internet. However that does not mean they are forbidden from being used by ISPs or corporate networks. As you pointed out it is common for ISPs to use the 10/8 block for edge routers. The "public" Internet does not begin until the ISP hands the traffic off at peering point. /tom

I just tested performing a trace route to 10.0.0.1 and sure enough, my router tried to send it out onto North State's (my ISP's) network. I was under the assumption that a home router would be intelligent enough to know about the private address space and not pass it LAN to WAN.
