According to Dmitriy Bokiy:
> Where can I find _the complete_ list of addresses to be blocked?

RFC-1918.

It includes the following networks:

        10.0.0.0/8 (in old pre-CIDR world, a A-class network)
        172.16.0.0/12 (in old pre-CIDR world, 16 B-class networks)
        192.168.0.0/16 (in old pre-CIDR world, 256 C-class networks).

Don't forget to refuse your own prefixes on your incoming interface... That
is, if you have a.b.c.d/n, you need to refuse this prefix on the incoming
interface of your router.
