Do you know whether your gateway is doing any sort of network address
translation?  It seems odd to me that you're getting an address range
that matches the external address of your modem, and that your external
address is a 10.x.x.x (since those are all non-routable private IPs).
I'd expect either the former if no translation is being done, or the
latter if your external address weren't private.  But seeing both at the
same time surprises me.

On my home system, for instance, my comcast cable modem is at 10.1.10.1
internally, but 173.163.240.62 externally.

I have seen DHCP assign different addresses to Windows than to Linux,
but in your case the gateway box should be grabbing its address for
itself, and giving your computer the other available address.
