My first hop beyond my border for my home connection is a 10-net
address.  Provider is RoadRunner.  So, yes, ISP's are using RFC1918
space for access networks, which probably also has some bearing on
the recent thread regarding the frequency of attempted lookups of
RFC1918 in-addrs.

The driving force behind the NC is the belief that the companies who
brought us things like Unix, relational databases, and Windows can
make an appliance that is inexpensive and easy to use if they choose
to do that.
