John,
I think you're right on your assumption on this. 

ie.) traceroute ...
1  host1-null.null.bellsouth.net (192.168.1.1)  5.256
ms  4.464 ms  3.102 ms
 2  66-23-199-97.clients.speedfactory.net
(66.23.199.97)  25.009 ms  9.632 ms  12.727 ms
 3  host-null.bellsouth.net (10.100.0.1)  18.597 ms 
21.780 ms  15.542 ms
 4  wan.speedfactory.net (63.243.34.193)  23.326 ms 
18.949 ms  16.845 ms
 
My traceroutes reveals that it does hit 10.100.0.1
(host-null.bellsouth.net) everytime (a router, I
believe). So it seems that speedfactory does one way
or the other share something from bellsouth but I just
can't figure out why my local ip's are being
propagated with bellsouth's data entries. 

..dig @ns.speedfactory.com -x 192.168.1.1

Also, it happens without printer/samba services.
