Blocking incoming packets to your WAN from any private scheme
of IP addresses -  10.0.0.0 – 10.255.255.255  172.16.0.0 – 172.31.255.255
and 192.168.0.0 – 192.168.255.255 - is a good idea. In networking terms
is called IP Spoofing meaning that someone using any IP from the above
range may deceive your firewall settings and interpreted as someone from
your internal network!!

Is there a singularity with these address ranges ?

Yep, those addresses are only for internal usage, they should not be routed in 
a WAN! thus blocking them is a good idea. Blocking 127.x.x.x on every 
computer/router/etc is a good practice as well, because         it should be used 
for only internal comunication.
