There is, RFC 1918 - Address Allocation for Private Internets although this
document is about the private address space (not loopback address).

It may not be coming from your ISP. My guess is, that you have cable internet.
If so, these packets are most likely from computers within the same network
segment as you are. Check the network mask of the IP of your uplink. If you
don't have a netmask equal to 255.255.255.255, the spoofed packets are most
likely NOT coming from your ISP. Everything packet travelling on that segment
is not subject to routing by your ISP.
Check the headers for your unsubscription address
