[Beowulf] A careful exploit?

[Jonathan Engwall]

Hello Beowulf,
Recently we had serious trouble with the internet. A technician had to
climb the pole. Another technician, an IT specialist in Mexico City, could
not resolve the issue, sent the man here.
Now trouble is back. What does this mean? Where are the missing IPs? From
the pole to the modem, to my repeater, to my machine, and then my VM gives
this using nmap:

Is this a new exploit?
Thank you,
