What do you mean by "no announcement for a network" exactly?
(kind of an alien term to me).

So no ASN result, means a "Bogon"?
A command like:
   location.py list-bogons --family ipv4

returns for example '1.236.0.0/18'. And
'location.py lookup ::ffff:1.236.0.0' returns an ASN:
   Network                 : 1.236.0.0/24
   Country                 : Korea, Republic of
   Autonomous System       : AS38396 - Paju office of Education Gyeonggi Province

Doesn't look like a "Bogon" to me.

And trying a 'nmap -sA -p80 1.236.0.0/24', gave me 11 hosts up.
Seems no router cares about Bogons.
