I am beginning to believe that One Communications has hijacked our address<br>
space. At the moment any traceroute from a Comcast cable modem in the<br>
Boston area to us dies somewhere in New York on a One Communications<br>
router. How do I approach them when I am not a customer? I took this up<br>
with our ISP (Windstream) and they declined to assist, as did Comcast. In<br>
niether case could I speak with a person who understood what was going on.<br>
<br>
Our IPs are in the range <a href="http://66.251.72.0/23" target="_blank">66.251.72.0/23</a>. The Windstream side of our router<br>
is 63.139.191.117. Traceroutes from Comcast to the latter do succeed, to<br>
the former fail. They take completely different paths. Traceroutes from<br>
inside our LAN to Comcast also fail, usually ending at a Level3 router in<br>
NY. None of the ISP mentioned here have a working looking glass.<br>
<br>
Thanks for any advice, suggestions.<br>
