man: Fix RFC 1918 network prefix lengths

Browse Source 
According to RFC 1918, the following IP prefixes are reserved for
private internets:

    10.0.0.0/8
    172.16.0.0/12
    192.168.0.0/16

This PR fixes the prefix lengths in references to private networks
("RFC 1918 networks", "the standard private IP address ranges").
The changes are limited to man pages.
